Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

(But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow.

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Class 10 pricing for Class 6 performance, June 10, 2010
Ran some of my own informal tests of this card pitted against an older well used Transcend Class 6 card. The older cheaper card equalled or beat this "Class 10" card. Shop for the best priced Class 6 card right now or pay the premium for real Class 10 performance.

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Great affordable SDHC card, March 28, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

My Canon loves the 8 GB SDHC card, January 15, 2008
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

Reliable card, good speeds!, December 4, 2008
Transcend 16 GB SDHC SD Class 6 Flash Memory Card TS16GSDHC6E [Amazon Frustration-Free Packaging]
I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera. I've run read/write tests on all of them and they get about 14 MB/s write speeds and 17.5 MB/s read speeds. Never encountered any errors! These cards are the best bang for your buck, and the frustration free packaging is awesome.

Don't Let This Happen to You....., August 3, 2008
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today? ... Read more

Beware, March 8, 2008
This is a must for loading music to listen to on my Palm TX. But BEWARE of eek Technoligies and buying at this price. They wanted $13.20 for shipping a 2 oz memory card? Buy from someone else even if it is a few dollars more and pay reasonable shipping rates. Don't be fooled by their cheap price they make it up 2x in shippoing charges. When I saw it I cancelled my order..

Make sure you can read it., December 24, 2007
Standard SD and SDHC cards look identical in size and shape, only SDHC-compatible products will be able to accept the new SDHC cards. SanDisk differentiates its new cards with the new SDHC logo on the card and retail package.

Now my web research finds that at the time of its release Wes Brewer, vice president of consumer product marketing at SanDisk, said, "In order to provide the easiest and most compatible solution for 4GB and larger capacity SDHC cards in the market, SanDisk chose to bundle its new MicroMate USB 2.0 SD/SDHC compatible card reader, which normally retails for $19.99, with this new card."

Note this deal does not include a reader.

In my case the device I bought it for can read it. Without the dedicated reader my year old HP computer cannot .

expensive SHIPPING!, March 23, 2008
I played around with the prices on this and found out several things. If I order this item, $11 in shipping costs is added by the third party supplier! If I get the 2G version, even two of them, those qualify for free shipping from Amazon and come out much cheaper. So check your prices on these before ordering. My hunch is that you can probably pick this 4G up cheaper at your local electronics/computer store...

Beware! does not work in many cameras, September 5, 2008
Finding that this product does not work in my one year old Canon camera I contacted the company and was given a list of cameras which do support it. This list belongs on the product description at the Amazon site. Besides the nuisance, I'll be out the $4.50 shipping cost for shipping an item requiring .59 cents postage.

Worked fine until it didn't work, December 15, 2008
I purchased this card five months ago and used it without incident. I was happy with the amount of space on the card. Suddenly today, for no apparent reason, a message came up saying "memory card error". I cannot access the photos on my card with my external card reader. I cannot use the card in my camera. The photos on the card are lost, and that makes me quite sad.

NOT compatible with Canon Powershot 590IS, September 9, 2008
The Sandisk site says this disk is compatible, and the user manual for the Canon Powershot 590IS says the camera can use SD or SDHC memory cards, so I assumed this card would be compatible. It wasn't. The camera says "memory card locked!" even when the card is unlocked. I'm giving this a one star rating because everything I looked at says this card is compatible, but it wasn't. For the Sandisk compatiblity site (which, of course, recommends their most expensive 32 and 16G cards first), see http://www.sandisk.com/Compatibility/Device(8725)-Canon-PowerShot_A590_IS.aspx . I haven't found a site so far that specifically recommends one card over another for this model of camera.

Love it!, May 6, 2008
I love it, it works as promised, and holds well over 30 minutes of video. Pops in and out of camera easily. It's a great product and worth the extra money over the 2.0 GB one.

Two thumbs up!

Works fine, October 29, 2007
Bought for a new camera and works fine. Many older SD card units won't handle 4GB and larger cards so make sure that yours will. If you are buying this for a PC there are USB adapters for these larger cards.

Great, April 3, 2008
This is a great addition to a digital camera if you shoot video clips.
Just make sure that the digital camera supports SD cards over 2Gb. You can usually be confident it will work if the device is labeled SD HC compliant (SD HC is the 4-32Gb standard). It may work in other devices (my Kodak camera is not labeled for SD HC but the card works.)

Never been disappointed, March 26, 2008

Reviews

Kingston quality, massive storage, what's not to love?, December 2, 2008
There are some things to consider before buying this particular card or any other 32gb SDHC card on the market:

1. This is NOT an ideal card for a digital SLR like a D80, D90, Rebel XT, etc... That is because it is a class 4 device. The class of a SDHC cards has to do with how fast they read and write files, not how much storage they have. For a digital SLR, you should purchase a class 6 SDHC card most of the time. Class 6 cards will allow you to take 'bursts' of photos and not be limited by the card's capacity to write them. Also class 4 cards are slower reading data, meaning they will take longer to upload files to your computer. Upload speed is convenient, especially when loading large batches of files.

2. This card has far more storage than most people will need for their digital camera. Unless you like to keep all your photos on a SDHC card and never move them to your computer, or are a high volume photographer, there is very little need for more than about 8gb of storage space for most caeras. The possible exception to this is if you have a professional SLR that shoots files in the 16-20mb range--but if you do, you'll likely want a class 6 card anyway. If all you intend to use this card for is a digital camera, save yourself a lot of money and buy a PNY 8GB SDHC Card. If you're worried about running out of space on a vacation, buy a few of them. Otherwise you run the risk of having 'all your eggs in one basket.' If one card fails, you lose all your pictures instead of only a portion of them.

This card is fantastic for use in a video camcorder capable of writing to an SDHC card. (Check with the manual first to insure that a class 4 card will be fast enough first). It is also perfect as extra storage for an ultra portable computer or net book like the Asus EEE pc. Another great application would be as added storage to a personal media player or MP3 player equipped with a SDHC slot such as the Cowon D2.

There are other good 32gb SDHC cards on the market, some at cheaper price points than the Kingston card. IMHO, brand matters very little with something like a SDHC card, since they all are made pretty much the same way. None of the brands currently offering them (Transcend, PNY, Kingston) have high fail rates with their other products, so I believe they are all pretty similar. What you decide to buy will depend on whether you trust a particular brand, or who has the lowest price. All of them will work equally well.

Very Big, September 8, 2008
PREFACE:

I bought this card for extra disk space on my Asus EeePC netbook. I needed as much space as possible to supplement the very small SSD hard drive. I needed something with large capacity and relatively fast file transfer time.

PROS:

It shares the largest SD capacity on the market today with few others (Panasonic, Sandisk, and PNY) and is a quality name that I have had a good history with in the past. Its file transfer time is similar to the SSD drive in my machine so it basically acts as a second SSD for me at less than a quarter of the price!

CONS:

Its not the cheapest 32gb SD card(PNY) nor the fastest(Panasonic) but its good quality with a decent transfer rate.

CONCLUSION:

I'm very happy with its performance and capacity. I would like to see the price come down a bit, but that's the price of getting electronics of this caliber.

That's my input, take it or leave it :)

Good for the money, but don't expect fast speeds., December 8, 2007
I didnt realize how fast the point and shoot cameras are getting sooo many megapixels until I started looking for a good one for my mom... This card is no good for a 12 megapixel camera! It takes way too long to save each picture slowing down how fast you're able to take consecutive pictures! Go for the Sandisk extreme cards and dont look back!

I only have SLR cameras, and use the San Disk extreme cards because speed is crucial! Dont cheap out on a card after buying a nice camera, or you'll be sorry! Thats the first thing i noticed when showing her how to use her new Canon Point and Shoot camera is how SLOWWWWWWWW it took to save each photo before I could take another.. If waiting a few seconds between each picture is a non-issue, buy all means save some money and buy this card.

Bottom line: You're wasting your money buying this card to use in a high resolution point and shoot, which they all seem to be now days. Just too slow!

Fast Card, November 21, 2007
I have this card. This is extremely fast card. I did a test on my laptop sd slot writing 6 gb files onto the card. Average speed was 5mb per second. that was more than it rated for.

If it was a little faster..., January 19, 2008
I contemplated a 4 star rating, but when you buy the card, you know that it is a "class 4" card, which means it's supposed to transfer files at at least 4GB/s. If it's crucial and you can afford it, you could get the "class 6" card, which would make a difference when transferring large amounts of data.

In short:
*Pros:*
- Capacity. You can get more capacity, but this is a bout the best size/price ratio.
- Price. Again, 8GB and 4GB cards have the best size/price ratio.
*Cons:*
- SDHC. This is not really a con if you have new equipment, but SDHC is a newer standard, so you have to make sure you have the right equipment - SDHC IS NOT THE SAME AS SD!!
- Speed. It's not "slow", but if you've had fast cards you'll notice the difference. Of course, you know this from the "Class 4" rating, so it's also not really a con.

I've owned 2 Kingston SD cards. The oldest of them is about 3 years old and is still as reliable and good as when I first got it, so I have reason to believe this card will last for a while.

My older Kingston 50X SD card is about twice as fast as this card, but it's only 1GB, so I needed more GB's to capture more video. This card would be just about perfect if it was faster. When I say that, I don't mean that the card is slow - my Vista machine can use it for ReadyBoost and camera performance is good. Just know that ReadyBoost can only use 4GB of memory, so you'll have 4GB of memory just sitting unused if you use it for this purpose.

Primarily, I use this card for recording video clips and pictures with my Canon cameras, SD800IS and A710IS. For that purpose the card is great. I haven't noticed any lag when taking 7.1 Mega-pixel pictures (which range from 1MB to about 4MBs) or full screen VGA video (640x480). Here's some general advice for these cameras in particular, but it applies to most cameras:
1. Don't record more than about 10 minutes of video at a time because the file size goes over 1GB, but this depends on the camera and video format, not the card itself.
2. You might want to get an external card reader, if you don't have an internal card reader. You'll be fine transferring files directly from the camera if you only take a few snapshots and short videos. But if you plan on truly using all 8GB and transferring them at once, do yourself a favor and get a card reader. Most cameras are not meant to read/transfer files at fast speeds (even if they're USB 2.0 capable), and at least with the SD800IS, I could not transfer files over 500MB. Once I used a memory card reader, transferring was a breeze.

Although reading times are fast enough (between 4-8MB/s), writing is a bit slower - it tops out at about 4MB/s, which is good enough for the "Class 4" rating and fast enough to capture pictures without (noticeable) lag in my cameras.
It's a great card for the price; just make sure you understand what you're buying.

Don't be swayed by idiot customers.., February 25, 2008
I like our point and shoot camera to be low thought-low effort (big SD card, high capacity rechargeable battery, reliable point and shoot performance, etc.), and this 16 gig card coupled with our Canon SD770 has been a great combination. Almost 1000 pics on our vacation to Punta Cana, and the card wasn't filled (I could do the math, but I don't want to).

The card has been reliable, worked fine in a card reader, and I'd make the purchase again. I can't believe this little card holds 1000's of times more information than information storage from only a short time ago, and cost me ~$20. Amazing!

Excellent for the price. I give it a 4/5 because it performs slower than expected from a C4 SDHC card. I also have a Sandisk EIII 2GB. Although it doesn't have the class ratings because it's not SDHC, the Sandisk outperforms the Kingston in both read/write.

My test scenario: Using a Nikon D80 taking 6 shots continuously. The Kingston took considerably longer to write contents from the Nikon D80 buffer.

If you're looking for a high speed card in a similar scenario, then look elsewhere. However, if you want a good card and no particular need for speed, then I recommend getting.

does the job, but not good enough..., December 23, 2009

The Kingston 4gb SDHC memory card, like all other Kingston products, is an exceptional piece of equipment. I use it with my Canon SD1000 and I get nothing but blazing fast write times and no headaches. Make sure your device supports SDHC because if not, it will not work. This is a key reason why people are left "unsatisfied" by what they get, not because of the product, but because they did not do their homework.

Buyers, you should really take note that, most reviews on any site about not only Kingston, but other great brands, is heavily altered by idiot customers leaving comments to attack the site that sold them the items. So don't quickly judge an product based on how many stars it has, because honestly, you cannot take that into consideration unless you have read every review posted.

great value at $22, December 3, 2007
The price of the SD4/4GB card jumps around a lot here. It is a great value at $22. Not so hot at $40. Wait a while and it may go down again. Note that only newer SD devices can use the 4GB SDHC cards. Older cameras, etc. can only use regular SD cards up to 2GB. If you're not sure, check your owner's manual or contact your manufacturer. Also, older SD card readers will not work with SDHC cards, but SDHC card readers are available for about $10 on amazon.com

Unreliable - Disappearing Pictures, December 12, 2008
I had this card in a Panasonic DMC-TZ5 camera for about a month, and in that time the card experienced a "read error" on three separate occasions that resulted in all the pictures currently on the card disappearing. I called Panasonic customer service and the first question they asked was what brand card I had. When I told them Kingston, they advised me to get a new card, as nearly everyone who complained about disappearing pictures (in any model camera) had a Kingston card. I'd much rather spend a little more money and actually have my pictures!

Editorial Review

Performance and capacity redefined with Kingston's SD High-Capacity memory cards.

Starting at 4GB, SDHC cards offer larger-volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingstonâ?TMs SDHC cards use new speed "class" ratings known as Class 2, 4 and 6 that deliver a minimum data transfer rate for optimum performance with SDHC devices.

Although identical in size to todays standard SD card, the new SDHC cards are designed differently and are only recognized by SDHC host devices. To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.).

For added reliability and durability, our solid-state SDHC memory cards are built of nonvolatile memory components and have no moving parts that could wear out or break. All cards are 100-percent tested and are backed by a lifetime warranty and free live technical support. ... Read more

Another great application would be as added storage to a personal media player or MP3 player equipped with a SDHC slot such as the Cowon D2.

There are other good 32gb SDHC cards on the market, some at cheaper price points than the Kingston card. IMHO, brand matters very little with something like a SDHC card, since they all are made pretty much the same way. None of the brands currently offering them (Transcend, PNY, Kingston) have high fail rates with their other products, so I believe they are all pretty similar. What you decide to buy will depend on whether you trust a particular brand, or who has the lowest price. All of them will work equally well.

PREFACE:

I bought this card for extra disk space on my Asus EeePC netbook. I needed as much space as possible to supplement the very small SSD hard drive. I needed something with large capacity and relatively fast file transfer time.

PROS:

It shares the largest SD capacity on the market today with few others (Panasonic, Sandisk, and PNY) and is a quality name that I have had a good history with in the past. Its file transfer time is similar to the SSD drive in my machine so it basically acts as a second SSD for me at less than a quarter of the price!

CONS:

Its not the cheapest 32gb SD card(PNY) nor the fastest(Panasonic) but its good quality with a decent transfer rate.

CONCLUSION:

I'm very happy with its performance and capacity. I would like to see the price come down a bit, but that's the price of getting electronics of this caliber.

That's my input, take it or leave it :)

Good for the money, but don't expect fast speeds., December 8, 2007
Excellent for the price. I give it a 4/5 because it performs slower than expected from a C4 SDHC card. I also have a Sandisk EIII 2GB. Although it doesn't have the class ratings because it's not SDHC, the Sandisk outperforms the Kingston in both read/write.

My test scenario: Using a Nikon D80 taking 6 shots continuously. The Kingston took considerably longer to write contents from the Nikon D80 buffer.

If you're looking for a high speed card in a similar scenario, then look elsewhere. However, if you want a good card and no particular need for speed, then I recommend getting.

does the job, but not good enough..., December 23, 2009
I have this card. This is extremely fast card. I did a test on my laptop sd slot writing 6 gb files onto the card. Average speed was 5mb per second. that was more than it rated for.

If it was a little faster..., January 19, 2008
I contemplated a 4 star rating, but when you buy the card, you know that it is a "class 4" card, which means it's supposed to transfer files at at least 4GB/s. If it's crucial and you can afford it, you could get the "class 6" card, which would make a difference when transferring large amounts of data.

In short:
*Pros:*
- Capacity. You can get more capacity, but this is a bout the best size/price ratio.
- Price. Again, 8GB and 4GB cards have the best size/price ratio.
*Cons:*
- SDHC. This is not really a con if you have new equipment, but SDHC is a newer standard, so you have to make sure you have the right equipment - SDHC IS NOT THE SAME AS SD!!
- Speed. It's not "slow", but if you've had fast cards you'll notice the difference. Of course, you know this from the "Class 4" rating, so it's also not really a con.

I've owned 2 Kingston SD cards. The oldest of them is about 3 years old and is still as reliable and good as when I first got it, so I have reason to believe this card will last for a while.

My older Kingston 50X SD card is about twice as fast as this card, but it's only 1GB, so I needed more GB's to capture more video. This card would be just about perfect if it was faster. When I say that, I don't mean that the card is slow - my Vista machine can use it for ReadyBoost and camera performance is good. Just know that ReadyBoost can only use 4GB of memory, so you'll have 4GB of memory just sitting unused if you use it for this purpose.

Primarily, I use this card for recording video clips and pictures with my Canon cameras, SD800IS and A710IS. For that purpose the card is great. I haven't noticed any lag when taking 7.1 Mega-pixel pictures (which range from 1MB to about 4MBs) or full screen VGA video (640x480). Here's some general advice for these cameras in particular, but it applies to most cameras:
1. Don't record more than about 10 minutes of video at a time because the file size goes over 1GB, but this depends on the camera and video format, not the card itself.
2. You might want to get an external card reader, if you don't have an internal card reader. You'll be fine transferring files directly from the camera if you only take a few snapshots and short videos. But if you plan on truly using all 8GB and transferring them at once, do yourself a favor and get a card reader. Most cameras are not meant to read/transfer files at fast speeds (even if they're USB 2.0 capable), and at least with the SD800IS, I could not transfer files over 500MB. Once I used a memory card reader, transferring was a breeze.

Although reading times are fast enough (between 4-8MB/s), writing is a bit slower - it tops out at about 4MB/s, which is good enough for the "Class 4" rating and fast enough to capture pictures without (noticeable) lag in my cameras.
It's a great card for the price; just make sure you understand what you're buying.

Don't be swayed by idiot customers.., February 25, 2008
The Kingston 4gb SDHC memory card, like all other Kingston products, is an exceptional piece of equipment. I use it with my Canon SD1000 and I get nothing but blazing fast write times and no headaches. Make sure your device supports SDHC because if not, it will not work. This is a key reason why people are left "unsatisfied" by what they get, not because of the product, but because they did not do their homework.

Buyers, you should really take note that, most reviews on any site about not only Kingston, but other great brands, is heavily altered by idiot customers leaving comments to attack the site that sold them the items. So don't quickly judge an product based on how many stars it has, because honestly, you cannot take that into consideration unless you have read every review posted.

great value at $22, December 3, 2007
The price of the SD4/4GB card jumps around a lot here. It is a great value at $22. Not so hot at $40. Wait a while and it may go down again. Note that only newer SD devices can use the 4GB SDHC cards. Older cameras, etc. can only use regular SD cards up to 2GB. If you're not sure, check your owner's manual or contact your manufacturer. Also, older SD card readers will not work with SDHC cards, but SDHC card readers are available for about $10 on amazon.com

Unreliable - Disappearing Pictures, December 12, 2008
I had this card in a Panasonic DMC-TZ5 camera for about a month, and in that time the card experienced a "read error" on three separate occasions that resulted in all the pictures currently on the card disappearing. I called Panasonic customer service and the first question they asked was what brand card I had. When I told them Kingston, they advised me to get a new card, as nearly everyone who complained about disappearing pictures (in any model camera) had a Kingston card. I'd much rather spend a little more money and actually have my pictures!

A great bargain, and didn't fill up after 1000 pics!, January 21, 2009
I like our point and shoot camera to be low thought-low effort (big SD card, high capacity rechargeable battery, reliable point and shoot performance, etc.), and this 16 gig card coupled with our Canon SD770 has been a great combination. Almost 1000 pics on our vacation to Punta Cana, and the card wasn't filled (I could do the math, but I don't want to).

The card has been reliable, worked fine in a card reader, and I'd make the purchase again. I can't believe this little card holds 1000's of times more information than information storage from only a short time ago, and cost me ~$20. Amazing!

Kingston quality, massive storage, what's not to love?, December 2, 2008
There are some things to consider before buying this particular card or any other 32gb SDHC card on the market:

1. This is NOT an ideal card for a digital SLR like a D80, D90, Rebel XT, etc... That is because it is a class 4 device. The class of a SDHC cards has to do with how fast they read and write files, not how much storage they have. For a digital SLR, you should purchase a class 6 SDHC card most of the time. Class 6 cards will allow you to take 'bursts' of photos and not be limited by the card's capacity to write them. Also class 4 cards are slower reading data, meaning they will take longer to upload files to your computer. Upload speed is convenient, especially when loading large batches of files.

2. This card has far more storage than most people will need for their digital camera. Unless you like to keep all your photos on a SDHC card and never move them to your computer, or are a high volume photographer, there is very little need for more than about 8gb of storage space for most caeras. The possible exception to this is if you have a professional SLR that shoots files in the 16-20mb range--but if you do, you'll likely want a class 6 card anyway. If all you intend to use this card for is a digital camera, save yourself a lot of money and buy a PNY 8GB SDHC Card. If you're worried about running out of space on a vacation, buy a few of them. Otherwise you run the risk of having 'all your eggs in one basket.' If one card fails, you lose all your pictures instead of only a portion of them.

This card is fantastic for use in a video camcorder capable of writing to an SDHC card. (Check with the manual first to insure that a class 4 card will be fast enough first). It is also perfect as extra storage for an ultra portable computer or net book like the Asus EEE pc. Another great application would be as added storage to a personal media player or MP3 player equipped with a SDHC slot such as the Cowon D2.

There are other good 32gb SDHC cards on the market, some at cheaper price points than the Kingston card.

None of the brands currently offering them (Transcend, PNY, Kingston) have high fail rates with their other products, so I believe they are all pretty similar.

does the job, but not good enough..., December 23, 2009
I didnt realize how fast the point and shoot cameras are getting sooo many megapixels until I started looking for a good one for my mom... This card is no good for a 12 megapixel camera! It takes way too long to save each picture slowing down how fast you're able to take consecutive pictures! Go for the Sandisk extreme cards and dont look back!

I only have SLR cameras, and use the San Disk extreme cards because speed is crucial! Dont cheap out on a card after buying a nice camera, or you'll be sorry! Thats the first thing i noticed when showing her how to use her new Canon Point and Shoot camera is how SLOWWWWWWWW it took to save each photo before I could take another.. If waiting a few seconds between each picture is a non-issue, buy all means save some money and buy this card.

Bottom line: You're wasting your money buying this card to use in a high resolution point and shoot, which they all seem to be now days. Just too slow!

Very good hard drive!, November 23, 2009
I work for Computing support at Arizona State University, and I have enough technical knowledge to be certified as a TECH JUNKIE :).

I am a photographer too, so I have tons of Photos (about 160GB), Videos, Software, Movies and Documentaries. I was looking for a simple external hard drive without any backup software included, I am smart enough to do manual incremental backups with file tree structure intact (I use GOODSYNC to backup, its very simple and easy to use and free).

I have looked at many many external HDDs and narrowed down to two models "Samsung Story 1TB - very good one too" and this one (I wanted it to be cheap too - got this for $85 on [...]). I did not go with other WD models because of their annoying Backup Software.

Coming to the WD Elements 1TB: Its much smaller than I expected. It is dead silent, I had to touch it to convince myself that it was running, when I first turned it on. Its not too heavy either. The indicator light is placed at the rear, which is a very good thing (I find these LED's annoying, especially at night).

After I did the first setup, I copied 383GB of data (931GB was total space). It took about 4hr 47min, speed varied between 20MBps to 37MBps. This is pretty good speed for USB 2.0. It was just a bit warm (my old segate hard drive would be very very hot for this amount of data transfer).

I would recommend it to beginners or pros alike. I am very happy with this purchase!


UPDATE:

After about three months of heavy usage, it never gave up on me. Its still dead silent and works flawlessly. It never got even warm!!

Follow these steps to get GOODSYNC for FREE:

In the beginning GOODSYNC was free, later they made a paid version as it gained popularity..

but there is a way to get PRO version for free...

1. go to good sync website
2. signup for a trial offer and you get PRO serial for free (I signed up for eMusic trial)
3. Once you get the serial, end the subscription before the trial expires...

NOTE: The above mentioned procedure may not work anymore :(

UPDATE: 07-28-2010

I sold my WD Elements 1TB and got a 2TB one a couple of months ago(as my data is on rise all the time), couldn't be happier :)
I bought it from TigerDirect for [ ... ] and got [ ... ] cashback via [ ... ] ...awesome!!

Excellent, well designed product for the money!, November 19, 2009
I bought this on sale at Fry's for $99, way below the amazon price. I wanted something simple as most hard drives these days come with their annoying built in software which cannot be deleted (like WD Essential Edition). This is a hassle free drive and is not bundled with any of the extra software which is exactly what I wanted. You simply plug it in and it works. It can easily be formatted to work with macs as well. I've been using WD hard drives for years and I own several models of the "essential" and "passport" editions. They are very reliable.

This elements hard drive has a sleek and sexy, minimalist design. It is well built overall and constructed of durable plastic. There is a slot for the USB cable, a slot for the power adapter and a tiny circular white light which blinks when it is in use (the light is not overwhelming as some hard drives can be). All three of these features are on one side/face of the hard drive (as shown in the picture), so if you have this plugged in and it is facing away from you, you won't see the light at all. This doesn't bother me but it may be a turn off for some people.

When in operation, it is very smooth and quiet compared to other WD hard drives I own. This may be due to the fact that it is closed entirely and there are no holes for ventilation as in other WD models. But this doesn't bother me because I just use this as a backup and don't need it on all of the time. This could (emphasis on "could") be an issue if you are constantly using your hard drive because it may become hot. I haven't experienced this at all, just speculating. If you are just backing up files and, say, watching a movie on your computer which is stored on the hard drive, I think you'll be fine and there won't be any heating issues.

Good value, no extra junk software!, December 2, 2009
I purchased the 1tb Elements (WDBAAU0010HBK-NESN) for use with a Dish DVR 622.

Installation was was truly "plug and play". I simply took it out of the box, plugged it in, and it was immediately recognized by the DVR. I have since transferred about 200gb of content to/from it, and have watched content directly from the drive. So far, it is working perfectly. It automatically spins down after a few minutes of non-use, as well as when the DVR is powered off. It also spins back up automatically (less than 10 seconds) when the DVR accesses it.

One thing some people might not like: The case is designed to sit flat (as pictured), not on its side. There are four small non-skid pads on the bottom corners, but none on either side. There is no indication on the box, in the documentation, or on Western Digital's web site as to whether the drive will work properly on edge. As a general rule, WD drives are designed to operate sideways or even upside down (any X,Y,Z orientation), so this one probably will too -- but you'll need to provide your own non-skid pads.

Several similar Western Digital drives, such as the late model "My Book" series, now include a firmware-based CD-partition that is difficult to remove, and can cause compatibility issues with some devices. That partition contains backup software and utilities that are of questionable value in any case, and of absolutely no value when using the drive with a non-computer device (like the Dish DVR). The Elements -- at least at time of this review -- doesn't include any of that junk. (Note: WD does have a downloadable utility to remove the partition from the other drives, but if you don't want that junk then save yourself the time/trouble and just buy the Elements drive.)

Register the drive with Western Digital to get the warranty updated !, December 16, 2009
I bought 3 of these drives for $99 each around Black Friday. The value cannot be beat and I always prefer Western Digital due to their Advance Replacement policy.
One of the drives had issues. I always check all new drives I buy with the Western Digital Life Diagnostics program which is available for free from Western Digital. All drives passed the test without issues. The test will take at least 12 hours to complete on such a large drive. One of the drives was dropping the transfer rate after copying 500 GB to it for no reason and I had to replace it. What is really disappointing is that the drive passed the test so I have no confidence in the diagnostic program anymore.

The moment you receive the drive check your warranty online at the Western Digital website. The warranty for this model is only 1 year which I consider absolutely insufficient for a drive. The bad thing about it is that Western Digital starts counting from the manufacturing date and by the time you get it, the warranty left is only 9-10 months which is ridiculous. They will update the warranty to 1 year after the purchase date but you will have to send them the receipt and be patient. It took them 2 weeks to respond to an online request. They also have an option to extend the warranty for another 2 years for $25 per drive. I might consider that....
I recommend this drive because the size, price and ease of use. It doesn't have any of the limitations of the fancier Western Digital drives. It is just a big, cheap external hard drive.


Update - September 16 2010

Today I bought another one and when cheking the warranty it was shorter by 6 months. I went through my regular procedure to write to WD Customer support when I realized they had a link that was addressing the issue. Now you can register the drive and it will update the warranty automatically. It even gives you 1 month more ! Also, the registration page gives information about warranty upgrades. You can upgrade this drive from 1 year to 3 years for $25. Not bad considering that if it dies after the first year (and all do after they are out of warranty) it is just a paperweight.

My advices to everybody that buy WD drives are:

1. Check your warranty ASAP.
2. Register the drive to get it updated.

Excellent External Drive, May 2, 2010
This is a great external hard drive for expanding your digital storage capacity. I was in need for added storage and wanted to go for the 2TB WD Elements External Hard Drive. I wasn't really happy with the prices I was seeing for the 2TB hard drive, and that is when I decided to check up on the 1.5TB drives. WOW! I was amazed at the price Amazon was offering these drives and I got two of them. Yes, two! (My work requires that kind of storage space)
I got 3TB worth of storage for the price of a 2TB External hard drive!

That said, let us talk about the performance of these drives -

1) Build and form factor - Nice sleek looking enclosures. All black, the sides are fingerprint magnets with a glossy finish. The top and bottom panels have a matte finish. Looks matter to me, even if it just an external drive. The microUSB and AC sockets are closely spaced with a small white indicator light besides them. All in all very compact, sleek, and aesthetically pleasing device.
2) Performance - I am getting constantly good speeds on these drives. Reads at 30MB/s and writes at about 24MB/s, which is good and fast enough for my needs.

As always, users have to be careful with all hard drives, internal or external. I am handling my drives with the utmost care. I don't want to lose any important data.

Finally, this drive is a complete value for money purchase. I say go for it if you are out looking for a large capacity external hard drive.

Very nice drive for a low price, November 23, 2009
I picked this up from Fry's when it was on sale for 100 bucks.
I like the price.
I think the main differentiators between this and the higher price drive is that it has only 1 year warranty, and does not come bundled with any software to help you back up stuff.
But seriously who uses any of those anyways? Drive is preformated to NTFS, if you have a mac you'll need to reformat to be able write to it.
what I like:
very small.-for a 3.5" drive. very quiet and does not vibrate as much as my seagate 1.5TB drives.-This maybe due to the drive running at a lower RPM. I couldn't find the SPEC to say what this drive spins at.
Drive spins up and down(powers down) when not in use. very nice. the white power LED isn't overly bright.
dislike: enclosure snaps together, making it hard to swap out the drive in the future. only 1 year warranty. but I think that the 1 year is pre-built into the pricing.

So far so good.., November 29, 2009
I was originally going to purchase the Western Digital WD Elements 1 TB USB 2.0 Desktop External Hard Drive (model WDE1UBK10000N). My sister in-law has that model and it truly is built like a tank. Metal case, rubber protectors on each end. It really looks like it could take few bumps. I picked up this particular model because I saw it on sale for $60 at the store that has a red bullseye for a logo. For that price I'd be silly not to snag it up.

As others mentioned it has a plastic case which is ok. Metal would've been nicer. And it is completely silent. Other than seeing the white light in the back blinking when transferring files, I cannot tell that it is actually working. But it is working :). I transferred 149 gb of data from my old external drive to this one in about 3 hours. It's usb so I'm used to relatively slow transfers. The true test will be if it lasts as long as my iomega external hard drive which I've had for over 6 years. Even though it's old, it has a small fan, an on/off switch, a long power cord and it feels like it can take a bump. I just needed a back up in the event the old work horse died on me.

Good:
+ cheap - $60 for "1TB" of storage space
+ plug and play
+ no annoying preloaded software
+ very quiet
+ barely warm after extended use(my old drive would get noticeably warm even with its built-in fan)

Not so good:
- plastic case. probably good idea not to lug this around too much.
- edges are shiny and attracts finger prints (this really didn't matter to me, but I thought I'd mention it
- short power cord ~6'4" (old drive's power cord is over 11'), though usb cord is a bit longer than my old drive (4'3" vs. 3'5"). It would've been better to add length on the power cord and shorten the usb.
- no fan

Price was the determining factor in choosing this drive over the "tank". If this can last as long as my old external hard drive then it will be $60 well spent.

UPDATE (11/29/09):
- actual storage space of 931 gb is a bit confusing at first. Per comments and some google searching 931gb is correct. Don't be alarmed when you first see the available space on your external hard drive.

Issues with Windows 7 Pro 64, June 2, 2010
I'm very glad I purchased this drive. The hard drive is enclosed in a somewhat heavy but simple metal case, and Western Digital seems to take great pains with their retail packaging to minimize shock without using excessive packaging materials. They are using a GreenPower drive in there, so it remains quiet, cool, and merely sips energy. However, do not expect this to be a speed demon. It runs at the same speed as your average notebook drive, so filling up a large capacity drive such as this one may take a long time. The drive also comes with the benefit (to me) of having absolutely no useless backup software preinstalled. The only real complaint I have lies with the AC adapter. I generally prefer a plug with the adapter separate. This one comes with a "wall-wart" which takes up far too much space on a surge protector.

I've had about 5 WD drives in the past, and of those 5 only one has failed me. All drives will eventually fail, and as such I see the company's ability to help you much more important than whether or not a particular drive fails. WD is one of those companies that is fairly reasonable when it comes to RMA and replacement of their products, so that's always a good sign.

Full formatted size for a 1.5TB drive is 1.35TB (as expected). Before placing anything valuable into something this large, I run Windows error checking, the company's diagnostic program (in this case WD Data Lifeguard found on their website), use full drive encryption by TrueCrypt to avoid being paranoid if I need to send it back for warranty, and finally I transfer and delete roughly a third of the drive's capacity a few times to stress test it. I've found that if a drive is to ever fail within a reasonable amount of time, this regimen will kill it and save me the trouble of an RMA in the relatively near future.

Very good hard drive!, November 23, 2009
I work for Computing support at Arizona State University, and I have enough technical knowledge to be certified as a TECH JUNKIE :).

I am a photographer too, so I have tons of Photos (about 160GB), Videos, Software, Movies and Documentaries. I was looking for a simple external hard drive without any backup software included, I am smart enough to do manual incremental backups with file tree structure intact (I use GOODSYNC to backup, its very simple and easy to use and free).

I have looked at many many external HDDs and narrowed down to two models "Samsung Story 1TB - very good one too" and this one (I wanted it to be cheap too - got this for $85 on [...]). I did not go with other WD models because of their annoying Backup Software.

Coming to the WD Elements 1TB: Its much smaller than I expected. It is dead silent, I had to touch it to convince myself that it was running, when I first turned it on. Its not too heavy either. The indicator light is placed at the rear, which is a very good thing (I find these LED's annoying, especially at night).

After I did the first setup, I copied 383GB of data (931GB was total space). It took about 4hr 47min, speed varied between 20MBps to 37MBps. This is pretty good speed for USB 2.0. It was just a bit warm (my old segate hard drive would be very very hot for this amount of data transfer).

I would recommend it to beginners or pros alike. I am very happy with this purchase!


UPDATE:

After about three months of heavy usage, it never gave up on me. Its still dead silent and works flawlessly. It never got even warm!!

Follow these steps to get GOODSYNC for FREE:

In the beginning GOODSYNC was free, later they made a paid version as it gained popularity..

but there is a way to get PRO version for free...

1. go to good sync website
2. signup for a trial offer and you get PRO serial for free (I signed up for eMusic trial)
3. Once you get the serial, end the subscription before the trial expires...

NOTE: The above mentioned procedure may not work anymore :(

UPDATE: 07-28-2010

I sold my WD Elements 1TB and got a 2TB one a couple of months ago(as my data is on rise all the time), couldn't be happier :)
I bought it from TigerDirect for [ ... ] and got [ ... ] cashback via [ ... ] ...awesome!!

Excellent, well designed product for the money!, November 19, 2009
I bought this on sale at Fry's for $99, way below the amazon price. I wanted something simple as most hard drives these days come with their annoying built in software which cannot be deleted (like WD Essential Edition). This is a hassle free drive and is not bundled with any of the extra software which is exactly what I wanted. You simply plug it in and it works. It can easily be formatted to work with macs as well. I've been using WD hard drives for years and I own several models of the "essential" and "passport" editions. They are very reliable.

This elements hard drive has a sleek and sexy, minimalist design. It is well built overall and constructed of durable plastic. There is a slot for the USB cable, a slot for the power adapter and a tiny circular white light which blinks when it is in use (the light is not overwhelming as some hard drives can be). All three of these features are on one side/face of the hard drive (as shown in the picture), so if you have this plugged in and it is facing away from you, you won't see the light at all. This doesn't bother me but it may be a turn off for some people.

When in operation, it is very smooth and quiet compared to other WD hard drives I own. This may be due to the fact that it is closed entirely and there are no holes for ventilation as in other WD models. But this doesn't bother me because I just use this as a backup and don't need it on all of the time. This could (emphasis on "could") be an issue if you are constantly using your hard drive because it may become hot. I haven't experienced this at all, just speculating. If you are just backing up files and, say, watching a movie on your computer which is stored on the hard drive, I think you'll be fine and there won't be any heating issues.

Good value, no extra junk software!, December 2, 2009
I purchased the 1tb Elements (WDBAAU0010HBK-NESN) for use with a Dish DVR 622.

Installation was was truly "plug and play". I simply took it out of the box, plugged it in, and it was immediately recognized by the DVR. I have since transferred about 200gb of content to/from it, and have watched content directly from the drive. So far, it is working perfectly. It automatically spins down after a few minutes of non-use, as well as when the DVR is powered off. It also spins back up automatically (less than 10 seconds) when the DVR accesses it.

One thing some people might not like: The case is designed to sit flat (as pictured), not on its side. There are four small non-skid pads on the bottom corners, but none on either side. There is no indication on the box, in the documentation, or on Western Digital's web site as to whether the drive will work properly on edge. As a general rule, WD drives are designed to operate sideways or even upside down (any X,Y,Z orientation), so this one probably will too -- but you'll need to provide your own non-skid pads.

Several similar Western Digital drives, such as the late model "My Book" series, now include a firmware-based CD-partition that is difficult to remove, and can cause compatibility issues with some devices. That partition contains backup software and utilities that are of questionable value in any case, and of absolutely no value when using the drive with a non-computer device (like the Dish DVR). The Elements -- at least at time of this review -- doesn't include any of that junk. (Note: WD does have a downloadable utility to remove the partition from the other drives, but if you don't want that junk then save yourself the time/trouble and just buy the Elements drive.)

Register the drive with Western Digital to get the warranty updated !, December 16, 2009
I bought 3 of these drives for $99 each around Black Friday. The value cannot be beat and I always prefer Western Digital due to their Advance Replacement policy.
One of the drives had issues. I always check all new drives I buy with the Western Digital Life Diagnostics program which is available for free from Western Digital. All drives passed the test without issues. The test will take at least 12 hours to complete on such a large drive. One of the drives was dropping the transfer rate after copying 500 GB to it for no reason and I had to replace it. What is really disappointing is that the drive passed the test so I have no confidence in the diagnostic program anymore.

The moment you receive the drive check your warranty online at the Western Digital website. The warranty for this model is only 1 year which I consider absolutely insufficient for a drive. The bad thing about it is that Western Digital starts counting from the manufacturing date and by the time you get it, the warranty left is only 9-10 months which is ridiculous. They will update the warranty to 1 year after the purchase date but you will have to send them the receipt and be patient. It took them 2 weeks to respond to an online request. They also have an option to extend the warranty for another 2 years for $25 per drive. I might consider that....
I recommend this drive because the size, price and ease of use. It doesn't have any of the limitations of the fancier Western Digital drives. It is just a big, cheap external hard drive.


Update - September 16 2010

Today I bought another one and when cheking the warranty it was shorter by 6 months. I went through my regular procedure to write to WD Customer support when I realized they had a link that was addressing the issue. Now you can register the drive and it will update the warranty automatically. It even gives you 1 month more ! Also, the registration page gives information about warranty upgrades. You can upgrade this drive from 1 year to 3 years for $25. Not bad considering that if it dies after the first year (and all do after they are out of warranty) it is just a paperweight.

My advices to everybody that buy WD drives are:

1. Check your warranty ASAP.
2. Register the drive to get it updated.

Excellent External Drive, May 2, 2010
The Western Digital WD Elements is probably most notable for what it doesn't have:

1) It doesn't have any clever "look at me" flasing/glowing/blinking lights. One tiny light in the back will confirm it is on. But you won't need to check because "it just works".

2) It doesn't have any annoying, auto-loading, "I know better" software. There are lots of great backup programs available (freeware, shareware and built into most operating systems). And, of course, you can always just drag-and-drop files right onto the drive.

3) It doesn't get hot. Heat is a killer for electronics so that is even more important than you might think.

4) It doesn't make ANY sound.

5) It doesn't take up much space. It is smaller and more compact than any other external drive that I have purchased.

6) It doen't have any goofy stands or attachments. It is squared on all sides except the back so you can position it any way you want to.

7) And finally, it doesn't cost much. Considering drive space for cost this is the best value I have ever gotten on a drive.

For reference I have purchased two Seagate Freeagent drives, a 1 TB MyBook and have put several old drives into external drive enclosures. All of them are still working. I also have passing experience with several others from work and associates -- I like the WD Elements solution the best!

Total value for money!, January 11, 2010
This is a great external hard drive for expanding your digital storage capacity. I was in need for added storage and wanted to go for the 2TB WD Elements External Hard Drive. I wasn't really happy with the prices I was seeing for the 2TB hard drive, and that is when I decided to check up on the 1.5TB drives. WOW! I was amazed at the price Amazon was offering these drives and I got two of them. Yes, two! (My work requires that kind of storage space)
I got 3TB worth of storage for the price of a 2TB External hard drive!

That said, let us talk about the performance of these drives -

1) Build and form factor - Nice sleek looking enclosures. All black, the sides are fingerprint magnets with a glossy finish. The top and bottom panels have a matte finish. Looks matter to me, even if it just an external drive. The microUSB and AC sockets are closely spaced with a small white indicator light besides them. All in all very compact, sleek, and aesthetically pleasing device.
2) Performance - I am getting constantly good speeds on these drives. Reads at 30MB/s and writes at about 24MB/s, which is good and fast enough for my needs.

As always, users have to be careful with all hard drives, internal or external. I am handling my drives with the utmost care. I don't want to lose any important data.

Finally, this drive is a complete value for money purchase. I say go for it if you are out looking for a large capacity external hard drive.

Very nice drive for a low price, November 23, 2009
I picked this up from Fry's when it was on sale for 100 bucks.
I like the price.
I think the main differentiators between this and the higher price drive is that it has only 1 year warranty, and does not come bundled with any software to help you back up stuff.
But seriously who uses any of those anyways? Drive is preformated to NTFS, if you have a mac you'll need to reformat to be able write to it.
what I like:
very small.-for a 3.5" drive. very quiet and does not vibrate as much as my seagate 1.5TB drives.-This maybe due to the drive running at a lower RPM. I couldn't find the SPEC to say what this drive spins at.
Drive spins up and down(powers down) when not in use. very nice. the white power LED isn't overly bright.
dislike: enclosure snaps together, making it hard to swap out the drive in the future. only 1 year warranty. but I think that the 1 year is pre-built into the pricing.

So far so good.., November 29, 2009
I was originally going to purchase the Western Digital WD Elements 1 TB USB 2.0 Desktop External Hard Drive (model WDE1UBK10000N). My sister in-law has that model and it truly is built like a tank. Metal case, rubber protectors on each end. It really looks like it could take few bumps. I picked up this particular model because I saw it on sale for $60 at the store that has a red bullseye for a logo. For that price I'd be silly not to snag it up.

As others mentioned it has a plastic case which is ok. Metal would've been nicer. And it is completely silent. Other than seeing the white light in the back blinking when transferring files, I cannot tell that it is actually working. But it is working :). I transferred 149 gb of data from my old external drive to this one in about 3 hours. It's usb so I'm used to relatively slow transfers. The true test will be if it lasts as long as my iomega external hard drive which I've had for over 6 years. Even though it's old, it has a small fan, an on/off switch, a long power cord and it feels like it can take a bump. I just needed a back up in the event the old work horse died on me.

Good:
+ cheap - $60 for "1TB" of storage space
+ plug and play
+ no annoying preloaded software
+ very quiet
+ barely warm after extended use(my old drive would get noticeably warm even with its built-in fan)

Not so good:
- plastic case. probably good idea not to lug this around too much.
- edges are shiny and attracts finger prints (this really didn't matter to me, but I thought I'd mention it
- short power cord ~6'4" (old drive's power cord is over 11'), though usb cord is a bit longer than my old drive (4'3" vs. 3'5"). It would've been better to add length on the power cord and shorten the usb.
- no fan

Price was the determining factor in choosing this drive over the "tank". If this can last as long as my old external hard drive then it will be $60 well spent.

Issues with Windows 7 Pro 64, June 2, 2010
Just received mine and it works with my HP LapTop under XP but although the drive shows up in Windows 7 you can't do anything with it. No Drive letter, no format, no nothing - device is working properly - you just can't use it. When you attempt to assign a drive letter in Disk Manager it complains that it needs a refresh which doesn't help.

After 5 or 6 Emails back and forth with WD they informed me to contact either my PC manufacturer or Microsoft to resolve the issue. After scouring the internet seems there are LOTS of people with this exact same problem under Windows 7 Pro 64 bit edition. (Most seem to have an NVidia video card as well.) Here's the fix (no thanks to WD):

1. Open Device Manager
2. Locate the Drive
3. Right Click - Uninstall
4. Unplug drive USB Cable and plug it back in

Transfers files at around 28 MB/sec. Other than this start up issue so far it's made a great back up drive.

Very nice hard drive with no excess frills., April 15, 2010

The hard drive is enclosed in a somewhat heavy but simple metal case, and Western Digital seems to take great pains with their retail packaging to minimize shock without using excessive packaging materials.

Sony Memory Pro Duo II - Fast But Expensive Memory for Your Sony Devices, June 2, 2008
At Least two of the Sony Packaged Memory's Pictured here on Amazon are FAKES or COUNTERFITS.

UNUSABLE MEMORY.

The people that make these are taking non-sony generic crap 512's, 1,2,or4 G size chips
and creating very elaborate nearly perfect (looking) FAKES! Zoom in and look very closely
at the model numbers for the 8 and the 16 Gig. In the third and forth images you can plainly see
the fake model numbers I have shown below.

Their numbers do not exist in the True Sony lineup.

for example: MSX-M8GST/X & MSX-M16GST/X do not exist <<< BOTH ARE FAKE

Dont believe me,, go look it up for yourself ,,, GOOGLE it or look at the links below.


THE NUMBERS SHOULD SAY

for MARKII MS-MT8G & MS-MT16G Also there is an 8g that is not MARKII it is MSX-M8GS/X << older model.

There is never a T toward the end of the model number in these particular Larger memories,
and NO MARKII's ever have a /X or a MSX !!! in the model # at all!
This fake erroneous numbering scheme was barrowed from the 1G MSPD which has the number > MSX-M1GST/X

and from what I can tell is the only Sony Stick to EVER have the T in that location!

Take the time to look at these links which are both VERY, VERY Informative on the Subject.

Works Great With PSP, March 24, 2008
This 16GB Memory Stick Duo II card works great with the PSP portable gaming system. It comes pre-formatted, so all you have to do is stick it into your PSP and go. In fact, there is a picture of the PSP right on the packaging.

The usable space on this device is actually 14.9 GB, however.

The "Mark2" certification on the card has to do with higher writing speed requirements and indicates the memory is certified to operate with AVCHD recording products.

Bought this for my PSP, May 15, 2008
This is currently the only available 16GB Memory Stick. I bought it for my Playstation Portable in order to replace an 8GB Memory Stick.
Regarding the price you can easily argue that it is much cheaper to buy two 8GB Memory Sticks. And for any person who is concerned about spending money I would not recommend this product.
At the time I bought it, Amazon was offering the best price online. Regarding the fact that this Memory Stick is about $50 more expensive than the PSP itself, makes you think twice. But my sole purpose was that I wanted to keep things together: my music, videos and saved games etc.
This Memory Stick is large enough to satisfy my thirst for disc space with a single solution.

The Memory Stick works fine in my PSP. Before this one I used a Sandisk 8GB Memory Stick Pro Ultra and I cannot see a difference in read/write speed (while connected through USB to my PC).

Final thoughts:
If you are concerned about spending money and you can live with more than one MS for your gadgets, you should get two or more 8GB MS. If you want a single solution and price is of no matter, get this one. Since it is from Sony you can be sure it works with your MS-enabled gadgets.

Pro:
- high capacity
- read/write speed is up to par with other (higher ranked) memory sticks (using the PSP USB connection!)

Con:
- not cheap

5 out of 5 stars; simply because the price does not matter to me

(My guess is that the price will drop to about $150 once other manufactures offer similar capacity.)

Fake 16GB memory stick pro dua from Amazon directly, July 15, 2009
I'm aparently also a victim of the fake cards. Ordered the 16GB Sony memory stick pro duo directly from Amazon. Received it (unaware of fake cards going around), formatted it in my PSP without problems. Then tried to load data to the card via my card reader. Card reader didn't recognize the card. Card reader was old so purchased a new one from Best Buy. Recognized the card but transfers were incredibly slow and data got corrupted. Checked with manufacturer of reader and they indicated they only tested up to 4GB. Bought yet another reader with guaranteed support for all speeds and capacities. Same problem. Checked online and found out about the fake cards. I already threw out the packaging believing the card readers to have been the problem. Amazon was kind enough to still ship me another card. Will wait and see if it is a genuine one. I would never have expected Amazon to be selling fake items...

Works great!, July 30, 2008
READ BEFORE YOU ACT!!! BEWARE OF FAKE CARDS!!!
I bought this Sony MSMT16G 16GB Memory Stick PRO Duo (Mark2) Media Card from one of Amazon "Featured Merchant". It came with a very original look like packaging, even a hologram on top. As soon as I insert it in to my video camera it did not recognized. I tried another same type camera and also a media card reader with no luck at all. Then I found lots of information on the net saying there are fake ones which won't work with cameras and else. So be careful don't buy a fake one, like me.

Real Authentic Memory card., July 14, 2008
I bought this mainly for my PSP. 16 gigabytes is very sufficient to store tons of movies and games and the best thing is there aren't any glitches at all. :D

16 Gigs of Satisfaction, July 16, 2008
I bought the Sony 16GB Memory Stick PRO Duo for my PSP and I feel like I almost have too much space for pictures, game saves, music, and movies. Because of the 16GB of storage space, my PSP now rivals my iPod Nano plus I can fit a hand-full of full length films on it. More storage space is definitely a good thing; I am very happy with my purchase.

Sony Memory Pro Duo II - Fast But Expensive Memory for Your Sony Devices, June 2, 2008

Even though I have been slowly weaning myself off of the newer Sony cameras, I still have some Sony devices that need memory pro duo cards. There are some advantages and a few disadvantages, namely the cost and availability. Sony's memory format averages 30 to 100 percent higher prices for the same capacity of SDHC cards. While that sucks, if you have a Sony Camera or a PSP there's not much you can do about it.

To that point, both the new Sony Cybershot DSCT300 Digital Camera and upcoming PSP God of War Entertainment Pack will benefit from any of these memory cards. Both of those devices, along with most Sony devices for that matter are only comaptible with the memory duo platform.

But like I said, if you need one of these cards, there are some advantages especially if you get a Mark II card. Namely, the performance speed of the mark II format is about 50% higher than the fastest available SDHC card at the moment. The rating is for 36 MB/s and what I've seen through some basic tests seems to indicate real performance close to this. In fact, the solid performance has to be the biggest pro for these cards. So while it sucks to have little choice, when you factor in the premium performance it's easier to swallow.

The 2 and 4 GB cards are a better value than larger capacity ones right now. Sometimes you want the largest card you can get, but till the 8 and 16 GB cards come down I see no reason to buy them. Not to mention, this isn't for my primary camera but for an older one that I use as a backup.

Make sure your device is compatible with the card. Some older electronics aren't compatible with larger capacities, although in general Sony has been better with making these guys backward compatible than others.

It's always a good idea to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card may be worth it if the price is right. Or you may want to step up to the larger 16 GB size that is now available. But if you wait a little longer you can save yourself some cash. I have to take off at least 1 star for value, but in terms of performance I couldn't be happier.

Enjoy!

Card reader was old so purchased a new one from Best Buy. Recognized the card but transfers were incredibly slow and data got corrupted. Checked with manufacturer of reader and they indicated they only tested up to 4GB. Bought yet another reader with guaranteed support for all speeds and capacities. Same problem. Checked online and found out about the fake cards. I already threw out the packaging believing the card readers to have been the problem. Amazon was kind enough to still ship me another card. Will wait and see if it is a genuine one. I would never have expected Amazon to be selling fake items...

Works great!, July 30, 2008
Purchased this for my Sony Cyber-shot DSC-W150 camera based on the 25 great reviews before me. (Thanks, reviewers... I wasn't exactly sure what I was doing because the documentation that came with the camera didn't provide any help on how to buy memory!) I thought $38.50 was a great deal. It does the job and allows me to record video clips without feeling like I'm eating up all my memory. (For reference, about a minute and a half of video uses up about 200 shots out of the 2,500+ shots. Though I don't know if the resolution settings, etc. are factored into that estimate).

READ BEFORE YOU ACT!!! BEWARE OF FAKE CARDS!!!
I bought this Sony MSMT16G 16GB Memory Stick PRO Duo (Mark2) Media Card from one of Amazon "Featured Merchant". It came with a very original look like packaging, even a hologram on top. As soon as I insert it in to my video camera it did not recognized. I tried another same type camera and also a media card reader with no luck at all. Then I found lots of information on the net saying there are fake ones which won't work with cameras and else. So be careful don't buy a fake one, like me.

Real Authentic Memory card., July 14, 2008
I bought this mainly for my PSP. 16 gigabytes is very sufficient to store tons of movies and games and the best thing is there aren't any glitches at all. :D

16 Gigs of Satisfaction, July 16, 2008
I bought the Sony 16GB Memory Stick PRO Duo for my PSP and I feel like I almost have too much space for pictures, game saves, music, and movies. Because of the 16GB of storage space, my PSP now rivals my iPod Nano plus I can fit a hand-full of full length films on it. More storage space is definitely a good thing; I am very happy with my purchase.

Great, just does its job, July 26, 2008
I have had this for a month and it works well. I call it "boring" as it ought to be. It just works and does not bother me. I have several and they have worked well too. This seems to be another of Sony's quality products. ... Read more

Sandisk 8GB SDHC Memory Card ... Read more

Reviews

Great Class 2 card, but make sure you have an SDHC reader., June 2, 2008
Please note that this is a Class 2 card (Class 6 is the current "top of the line"). Class 2 transfers two mega-thingies per second rather than the six mega-thingies per second for Class 6 cards.

This transfer rate is fine for most devices, but takes 3 times as long to copy files back and forth from your computer.

Please also note that older card readers are not able to handle SDHC (HC stands for "High Capacity"). Some card readers are good for only 1 GB, some go up to 2 GB or 4 GB, but only the latest generations are capable of 8 GB.

Lastly, if you are using Windows XP, you may need to either add Service Pack 3 or add a patch before the high capacity card can be recognized by your system.

I recommend adding the patch rather than SP3. Some things haven't been working quite right since I installed the latest service pack from Microsoft - you may not wish to take that chance...

Sandisk 8GB SD Memory Card Works Well, March 25, 2008
8GB is more than enough for my Canon PowerShot. I recently went to New York City for vacation and took more than 250 plus pics with the best pixel quality the camera could provide and still had more than enough memory left. Highly recommend this product. You don't need to carry any extra memory.

8 gig SDHC card works very well!, March 25, 2008
I found the performance excellent and the size very compact to carry about without difficulty of damage or weight reduction on travel. The price too is very competitive compared with in-shop prices.

Great Product, July 6, 2008
This is the best value for the quality for a SD card of this size. I Highly recommend this to anyone that needs storage. I purchased this for my Nikon D40 Digital SLR camera, and it works beautifully. I have plenty of room to storage photographs.

Works as it should!, July 1, 2008
What can I say? This product works perfectly in my Canon FS100 camcorder. No issues with corrupt data (knock on wood) and the write speed is adequate...no delays noticed during camcorder use. Sure, there are cheaper SDHC cards out there but I have used Sandisk in the past and have never had a problem with them.

8Gb memory for camera, June 30, 2008
Great so far. I went to an air show in Anchorage and I was able to do a lot of videos.

Beware, December 4, 2010
The price looks good but this company eats you alive on shipping in my opinion. I received 2 SD cards ( 1.2 x 2 x 3.8 inch total, this counts their clear protective slips, and these were shipped in a 5 x 8 bubble mailer using USPS First Class. For this the company charged $11.90. REALLY? COME ON.
Do not fall for this. Amazon needs to address these guys who overcharge for S/Handeling or face customers moving on.

SanDisk 8GB SDHC problem, September 16, 2009
This card was purchased in 6/09 for use in a new Canon 780IS camera that IS sdhc compatible. At first it worked great and it was wonderful to have such a large amount of memory available for stills and video. then after about a month it got glitchy and I received intermittent memory card error messages that would resolve by removing and reinserting the card. After another 2 weeks it is useless, won't read, won't write not in the camera nor in my computer (where it worked fine before). It's not the camera because all the other SD/SDHC cards I've tried work fine. I know Sandisk has a 5 year warranty, but like a trusting person I did not keep the receipt so I guess that's that. Pity because i have never had problems with Sandisk products before. ... Read more

For now, this is the best the US has, January 31, 2009
This micro SDHC card is the best in the US market. Samsung has developed a 32GB one but it is only available in Asia at the time of this writing. With that said, this is a good card. I bought it for my Blackberry Curve 8300. If you are going to use it for a Blackberry, make sure that you have the Blackberry OS 4.5 or later as it will not read the whole 16GB if you do not.

Even though this is a Class 2 card (the 16GB Class 4's, like the 32GB cards, are only available in Asia right now), it reads and writes fairly quickly. The card is fast enough to record and play videos on my Curve, and saving a couple minute video after shooting it literally takes seconds to write.

I have two minor gripes about this card, and they aren't that bad. One is the price. You can get an 8GB card for less than half of the price of this one. However, it is still "new" so that's the penalty for being an early adopter.

The other gripe I have is that with the Samsung reader (see the bundle Amazon sells with this card) will NOT format this card in anything other than FAT32. Now the Curve can't understand NTFS, so for me it's not a big deal, but for someone who may want to use this as take away storage, just be aware of that.

Other than that, I think this card is great. Also please note this card DOES come with an SD adapter. Don't let the Bulk Packaging fool you. If you have an SD card reader, you will not have to go out and buy a separate card reader for this. Save yourself the 5 bucks if you can. I hope this review was helpful.

Works with a Sansa Fuze, March 28, 2009
The card arrived when they said it would. Took it out of the box and stuck it in my MP3 player, the Sansa Fuze (2GB model) and it recognized it immediately and I was able to start putting music on it (didn't need to format it). I put about 10GB of music on it which took roughly 2 hrs to load. After the initial upload of all my music. Adding a new album only took a couple of minutes. After I disconnect the Fuze from the computer it took approx 8-10 minutes to refresh the media library. I have the latest firmware update for the Fuze (maybe older firmware versions are slower - I don't know). The upload speeds didn't bother me because I'm only loading my whole library once and then its only a song/album or two at a time and that's only a few minutes. The card came with a SD adapter - so if you have a SD reader your set. I now have a 18GB MP3 Player!

Beware high failure rate of this card! :(, May 25, 2009
I bought this card in February 2009 and it eventually failed by May 2009. I have of course only anecdotal evidence, but if you search around the Sandisk support forums and other places, you will find a lot of very upset customers complaining of the high failure rate of these Sandisk 16GB SDHC cards after a 2-3 months of use. To compound the problem, Sandisk only offers a 30 day return or refund period warranty on their flash memory cards which is atrocious in my opinion!! Unfortunately, most resellers here on Amazon only have a 30 day return policy as well assuming you have the product still in the original packaging. So overall, you are screwed if and WHEN the card does eventually fail. Thus, I recommend you not rely on this card to store important data like pictures and such. I unfortunately found this out the hard way. It just seems that this card is just not as reliable as advertised, and I am quite disappointed in the lack of at minimum one year manufacture's warranty for these cards by Sandisk. Buyer beware!!

Great at the time but go for at least a class 4 now, July 29, 2009
I bought this six months ago (in January 2009) because it was the only 16GB micro SDHC card available. I needed it to dump as much of my music as I could onto my BlackBerry Bold. It has worked fine for the most part. However, if I were buying such a card today, I would search out at least a class 4 card and probably a class 6, both of which are now available here on Amazon (A-DATA MicroSDHC 16GB Class 6 Turbo With SD Adapter 16GUSDHC6 (Black); Sandisk 16GB Ultra microSDHC CLASS 4 / MobileMate micro Reader (SDSDQY-016G-S11M, Retail Package)).

To the extent that it is a problem, my BlackBerry scans this class 2 card when I do a restart -- and is sluggish during that time -- so because I have almost the entire card filled up, it can take the BB a good five minutes to scan the card because a class 2 card has a slower read speed. That's a good five minutes of unwanted sluggishness after a restart. A faster class 4 or 6 card would reduce that time considerably.

I wish that I had noticed that it's only Class 2 memory, February 2, 2009
I bought this memory for my HTC Touch Pro. I wanted to sync my music with windows media center and backup another USB flash drive. This card should only be used for occasional file transfers. The class 2 card is painfully slow to sync anything. I would have gladly spend more money for a faster Class 6 microSDHC card if I was paying attention at the time of purchase.

Works great in my EVO 4G, July 2, 2010
Bought this to upgrade my EVO 4G Android smartphone and have no complaints, works perfectly. Good value for the money (and now they're even cheaper!). Note when I bought mine it was delivered directly from Amazon (which I wanted as there are counterfeit cards out there).

Roomy and fast enough, September 12, 2009
I learned recently that all is not equal when it comes to SD storage. Some cards are far faster than others, and that can make a big difference in some applications. But this one is just sitting in my phone storing MP3s and files, and speed is never a big deal here, so it's okay that this is a middling-speed card. Plenty roomy for lots of stuff, too, at a good price.

Fake Card, November 10, 2010
I Ordered This SD card thinking it was a great deal almost too good to be true well that's exactly what it was, I got the card and my phone (which does read SDHC cards up to 16 GB) would not read the card. I ended up buying one at Wal-mart and compared the two cards and you could clearly see that the writing was a little different on the 16gd card I'm of the strong belief that it was a counterfeit card, thank fully I got a refund on it but it took Threatening to file a A-Z report to get some action out of the seller, I will Never Buy any electronics from Amazon again this is the second time this type of thing has happened to me last time it was with a Memory Stick DUO for my PSP and that time I didn't get my money back.

FAILED after only a few uses., March 20, 2010
I bought the SanDisk 16 GN Flash Memory card for use with my VHOLDR camera. To say that it took 3 months to fail is misleading. I only actually recorded on it a handful of times, maybe a dozen or so, before it failed. Extremely disappointed.

Great for my Blackberry 8900!, June 9, 2009
Indeed this is a class 2 micro sd (hc) card but for syncing media and storing files on my blackberry it is perfect. Class two (2) cards are generally meant for storage and not a lot of back and forth transfers as they have a high failure rate in that scenario. However, if you are going to sync media once in a while and just update your music/podcasts/audiobooks and pictures then this card is perfect.

It is a bit expensive...but you are getting 16gb and that is a lot of storage...all things considered.

The packaging is in one of those foil bags and it does come with a regular SD adapter to stick into a memory card reader.

I have used it in a Blackberry Bold and now the Blackberry 8900 and it works perfectly. I have not really noticed the speed degradation... The initial sync of all of my media (9gb) took a while...but that would take a while on anything....now with regular updates it is quick and easy and thus Highly Recommended. ... Read more

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk.

Depend on what you will use it for ..., October 13, 2010
The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

Cut the story short, I really want to see if there is any difference in writing performance between the 2 cards in a compact camera. There is a continuous burst mode in LX5 and the manual indicated it is only limited by the condition of picture environment and performance of the SD card. Within the mode there are 2 different settings:1) speed priority or 2) picture/quality priority. The shutter speed is much faster with speed priority compare to picture priority.

I first formatted both cards out of box then put each card in series of test(3 rounds each setting for each card) shooting at the same object under same lighting condition. The results:
Speed Priority:
SanDisk Class 10 8gb
22-33 shots before camera stopped to allow the card to catch up with writing.

Transcend Class 10 16gb
22-24 shots before camera stopped to allow the card to catch up with writing.

Picture priority
SanDisk Class 10 8gb
34-46 shots before camera stopped

Transcend Class 10 16gb
27-33 shots before camera stopped


It seems that at a higher shutter speed, both cards performed very similar under the same shooting condition. But at a slower shutter speed the SanDisk definitely out perform Transcend. I hope this little experiment satisfied anyone with curiosity like me. Transcend definitely is a bargain with 16gb and almost half of the price compare to SanDisk. But I am going to use SanDisk Extreme as my primary card and Transcend as backup or on a second camera to ensure i would not miss any shots.

Depend on what you will use it for ..., October 13, 2010
On my Panasonic GF1, it's the same speed as a Class 6 Transcend card and much slower than a Class 10 SanDisk Extreme. Buy the Transcend Class 6 if you want to save money or the SanDisk if you wan speed, but skip this one.

Not All Class 10 Cards are Equal, April 11, 2010
UPDATE 9-10 I own 4 of these cards now. I have more of these than any other card I own because the are a very good value for capacity/price/and speed. My initial dissapointment over the lack of super high speed is outweighed by the reality that this card is an exceptional value.

Origional Review:
I purchased this card making the assumption that all class 10 cards had the same read and write speed. This was a poor assumption on my part.

The product photo on Amazon does not have the card's speed printed on it. The card that was shipped shows the front of the card printed with "20MB/s" which is the cards read speed. The cards write speed is only 16MB/s.

I own a SanDisk Extreme III class 10 card that has (up to) 30MB/s read and write speed. My Nikon D-90 that can take advantage of the SanDisk cards speed. The difference is the SanDisk card can capture 100 photos at fine resolution in 24 seconds. The Transcend card captures 66 photos in the same time/resolution.

I reality very few people will ever have the need to drill off 100 photos in 24 seconds, but I can't stand to loose a good shot because the camera is slow while writing to the card and I can't fire the shutter. You can hear this happen at about 4.5 seconds in the video review. This does not happen with the SanDisk class 10 30MB/s card.

A lot can happen in a fraction of a second that can make a shot good or bad and the having ability to fire a lot of shots in rapid succession is important to me.

If you own an SLR that is capable of rapid fire, high-resolution photography you may want to consider the SanDisk Extreme III 30 MB/s card.

If you own a compact digital camera, this card will exceed the capabilities of all of them. For compact cameras the card isn't usually the slowest part of the data write process, it's the camera.

This card is reasonably priced for a class 10 card. Just know what you are getting, what your needs may be, and what else is available. I own other Transcend cards and they have always worked properly without any issues.

The video that I attached shows this card with the same 24 seconds that I gave the SanDisk Card.

Sandisk SDSDX3-008G-E31 8GB Extreme III SD Card 30MB/s (RETAIL PACKAGE)

Fast!, April 8, 2010
I purchased this for use with my new Canon T2i. I use it primarily for shooting full resolution 1080p video, although I shoot stills as well.

The camera choked on the class 4 chip that I originally purchased, but with this one, it is amazing. I can shoot rapidfire 18 megapixel stills (I've tested it up to 30+ shots in a row), and there is no lag. I've never had an error when shooting hi-def video.

Highly recommended! I'm buying another one.

Fast, fast, fast!, March 15, 2010
I bought this card for my Canon T1i. The card I had been using before ordering this one was a Kingston Class 6 micro sd card and it worked well enough for the type of shooting I did. Class 6 was the card speed that Canon recommended when I bought my T1i (Class 10 cards were not yet available) and it seemed fast enough for the way I used my camera - isolated single photos taken at Medium (8 MP) or Large (15 MP) jpg settings and 1280 x 720 video. And while I ocassionally took continuous photos, I had never much exceeded 5-10 photos in a row and had never run into a problem with my Class 6 card.

When I first saw the Class 10 cards I did some experiments with my camera. How many continuous Large photos could I take before the camera slowed down? It turned out to be about 30. And how many RAW photos could I take before the camera slowed down? It turned out to be about 9. SInce I did not generally take any photos in RAW and never needed more than about 10 continuous photos at Large, the Class 6 card seemed more than sufficient for my needs. But I wondered about the speed of the Class 10 cards enough that I finally bought one.

It turns out that the Class 10 card is sufficiently fast that there does not seem to be a reasonable upper limit on single Large photos. I have taken 60 on continuous without an issue. And although I still cannot take more than 9 RAW photos on continuous with the Class 10 card, when I am finished taking those photos the camera no longer displays a Wait - writing pictures screen. The RAW photos get written from the built-in memory to the card so quickly that the camera does not need to display the Wait screen.

So this card is fast! Given the way I take photos this purchase was unnecessary, but still I am glad I bought it. I know I will not run into a situation where speed is an issue with this card.

Transcend vs Sandisk of equal price, July 31, 2010
OK. this card was around $47 for a class 10 16gb. The other card i bought was a Sandisk class 10 8gb for the around same price. I did a 10 sec stop watch test on both cards with my Rebel T1i on raw and the Sandisk was only faster by 1 shot in a 10 sec burst. to me it seems trivial to pay 47 bucks for a Sandisk 8gig when you can get 16 gigs for the same price. yes i know, the Sandisk is good for arctic and desert temperatures... but i live in western NY... not Antarctica or the Sahara. If your looking for a good card, with more gigs for your buck, the Transcend is well worth it.

Slower than slow on Pentax K-x, April 25, 2010
I bought this for my pentax K-x but it would randomly corrupt images. Also, it was slower than my 3+ year old SandDisk Ultra 1GB card. I was told by the seller (Thememstore) that others with the k-x have had the same problems. So apparently it must have something to do with the class 10 part, because since I returned this card I bought a SandDisk Extreme III 4GB Class 6 and it works far better.

Would I recommend this card? Yes, but only to someone who knows that class 10 will work in their camera. I don't fault the card as I think the problem is with the K-x.

DESTROYS DATA -- after working fine for just long enough to fool you!, November 6, 2010
SUMMARY:


DO NOT BUY THIS CARD UNLESS YOU WANT TO PLAY RUSSIAN ROULETTE WITH YOUR DATA. Card worked fine when I bought it, but malfunctioned within the first 400 photos -- malfunctioned so badly that some very technical tools were needed to recover anything at all, and some photos were still permanently lost. Recovering the data requires the attention of a serious data recovery expert or someone with substantial technical knowledge and lots of time.


DETAILS:

I made the mistake buying this card for my camera right before a long trip overseas. It worked fine on the first few dozen shots. I didn't see any improvement in speed over my trusty 1.5-year-old Transcend 8GB Class-6 card, but that was most likely because the camera itself (Canon EOS Rebel 1000D/XSi) could not write images any faster than that (full-size JPEG, continuous shutter mode, roughly did ~2.5-3 images/second on both cards, with no slowdown after the first few shots).

200 shots or so into using this card, I get a sudden mysterious message from the camera when I try to take a new shot -- Card Format Invalid (never saw it in the previous 1.5 years on this camera with 3 other SDHC cards). I look around for a bit, and discover that turning the camera off, pulling the card out and putting it back in is enough to clear the error message, and the previous photos are still visible.

I then make the mistake of assuming the problem is just that -- needing to "reboot" the camera when the card is acting stupid, and nothing else. Over the next 200 or so shots, this problem comes up every 50 shots or so. Then, after yet another "reboot", I notice that the camera's playback function is only showing the last 30 photos!!! Yet it shows that there's only 5.7G of space left on the camera -- the other 2G+ _should_ be taken up by the photos I've shot thus far, but the playback doesn't show them.

And this happens in the middle of a trek through the Peruvian Andes, several days' walk/horse ride from the first village with electricity, let alone a computer (with lots of once-in-a-lifetime shots on the camera). I pull this card out immediately, plug in my backup card, and wait until coming back to civilization to take a look at the card. Sure enough, the card is severely corrupted -- the directory listing is showing a bunch of folders with weird-character names, and only the last ~30 photos are visible from the computer, too!


RECOVERY SUGGESTIONS:

Hopefully you'll read this before buying and will not buy this piece of junk card. If you had the misfortune of running into the same problem and losing your data, read on.

I have now had time to examine what was left on the card, using tools that are not easily usable to people without substantial technical training. I've managed to recover over 90% of my photos, but this was NOT easy, and I suspect that even some shops specializing in data recovery from failed disks may not know how to get your data back -- this is NOT as simple as just undeleting a file!

Non-technical instructions:

1. As soon as you see the FIRST error involving the card format, turn off the camera, pull out the card, and copy all of your photos to a different device (computer/harddrive/whatnot). The earlier you stop using this card, the safer your photos will be.

2. As soon as the first problem happens, move the little plastic slider on the side of the card to the "Lock" position -- this will prevent anything else from being written on the card, which lowers the risk of what's left of your photos being overwritten.

3. If you see directories (aka folders) with weird names when you plug this card into a computer -- or see a huge number of photos missing when you look at them on the camera, take the card out IMMEDIATELY, and take the card to a data recovery shop or a technical expert willing to look at the card in depth. Give them a printout of the explanation below.


Technical details:

At least in my case, the filesystem was indeed somehow damaged, perhaps by the camera deciding to write over the location of the root directory somehow. I took a full disk image of the card, and operated on the disk image only (there were no read errors when making the image, FWIW). Somehow I was lucky enough to have the original _subdirectories_ \DCIM and \DCIM\100CANON survive on the card intact even though the root directory structure now pointed to a different, new, place on the filesystem as \DCIM.

I found the location of the old 100CANON directory on the filesystem by searching for one of the filenames I knew would exist in the old directory, like IMG_7000, across the whole disk image.

I then edited the filesystem (yea, with a hex editor!) to have the new \DCIM directory point to the old 100CANON subdirectory. See the Wikipedia article on FAT32 for a reasonably easy reference on how to find the 4 bytes that need to be edited, and how to calculate the correct updated value.

Mounting the edited disk image (with Linux's 'mount -t loop'), the directory was intact, and all but about 5% of the photos were completely intact as well -- the remainder must have been overwritten after the directory structure got corrupted. Depending on how long it takes the user to notice a problem, of course, much more damage could easily happen to the original data.

Here's one easy hack to see how much you can hope to recover, if you're recovering camera data. The same trick may be useful for locating the JPEGs if the original image-containing directory is no longer intact (good luck with recovery then! I thankfully didn't have to do this). Take any image produced by the same camera, look at its JFIF headers. My camera leaves the string "Canon EOS DIGITAL REBEL XS" in two places in every JPEG it creates, early on in the JFIF header. Search for that string across the whole filesystem. If there's, say, 500 hits, that means you can hope for [easy] recovery of at most 250 photos -- any photo that is missing the JFIF headers will be missing the first chunk of the file, and will make it very hard both to find _and_ to reconstruct the remaining data, if any, into a usable JPEG (I have not tried to do this, at least, and it seems very hard).

Transcend Vs. Sandisk on Panasonic LX5, November 12, 2010
I will be writing this review for both SanDisk Extreme SDHC class 10 8gb and Transcend SDHC class 10 16gb.

I bought SanDisk class 10 and Transcend class 10 for my new Panasonic LX5. I got both card because no one really did a comparison with a compact camera and I was just going crazy trying to see if there is any big difference between the 2 cards.

SanDisk Extreme package box indicated it's water proof, x-ray proof, shock proof, temperature proof. I am not ready to spend $50 to see if it really stand up to it's words. And I don't think normal people would go through the extreme condition in taking pictures or videos.

The "C10" is for "minimum sustaining speed" of 10mbps. The sustaining speed is critical if you're using for HD camcorder. There is other brand card that is also c10 but it costs more (2x) for its print of 30mbps on the card. It leads consumers into thinking that the higher price is worth for the 30mbps. However, the 30mbps is the "burst" speed. Burst speed is critical for HD camera and for doing copies. I have a HD camcorder and I'm very satisfied with this card after many hours for recording. I bought this card to do 100% of recording so it is the right price. I would buy the other high price brand card of 30mbps if I will do a lot of picture taking. The bottom line is to buy for the purpose of your usage.

Not very fast, April 14, 2010

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

Transcend 32 GB SDHC Review, May 25, 2009
Before you drop 120~$ for a SD card ask yourself, Do you really need 32GB card? because the card itself with same specs costs only 35$ for the 16GB version, anyway here is info that might help you

Pros :
1- Class 6 Card the(guaranteed minimum Read/write speed of 6MB/s)
2- My Test Results 18.2-18.5MB/S Read - 11.6-11.8 Write (very stable)
3- Faster than average cards and almost close to top speed SDHC cards
4- 32GB in a single small chip is awesome(You can use it as a portable HD once in a while, i share some stuff with my friends with it sometimes


Cons :
1- Expensive
2- You can get two 16GB cards for around only 70$ and save yourself 50$~
3- Slow write speeds for a 32GB card (Takes forever to fill it with DATA from PC, its not the card fault though , its just the SDHC technology is getting old and slow for 2009 standards , time for newer Tech)

* Important Info

Avoid the Sandisk Ultra Series they never reach the true marketed speed "15MB-20MB/S" its just in theory speed like how everybody knows that USB2 is much slower than its specs, and they are only Class 2 for the 32GB version which will drop frames from your HD video (Plus Class 4 is minimum requirement for shooting in HD ) if you plan to get San disk Card then get the Extreme III Series (but again from my own Tests there read speed is about 20MB not 30MB and the write speed is 14MB/s~ instead of the transcend 11MB/s write speed (Unless you spam shooting pictures with your DSLR you don't "need" faster speed)

I bought This card because i plan to take videos with my HD camcorder that last more 2 Hours, if you do not plan to shoot for longtime then you are better with getting the 16GB card HOWEVER, if you are lazy like my mom and do not plan to transfer DATA from the card to Your computer HD after every trip, then get the 32GB card.or you gonna end up on a trip and a message pops "No memory"

If you plan to shoot for longer time, check your camcorder battery too does it even last that long? so be sure about that before you drop over 100$ for this card

product failed., July 26, 2009
I recently purchased a Canon Powershot A720IS digital camera that is capable of recognizing and using up to 2 TERRABYTES of memory card (in the future) so I wanted to get the largest memory card I could install for now. I wanted to use the camera both on dry land and with an underwater housing for shooting stills and video on dive trips. Camera specs said an 8 GB SDHC card would record one hour of hi res video at 30 fps. Or nearly 2300 hi res stills at 8 megapixels.

A test of the Transcend 8GB SDHC card in the camera ended up shooting 70 minutes of full screen, 30fps digital video that could not be distinguished from my DV camcorder video quality. Playback from the memory card to the TV was so fast & efficient there was never a single "stutter" on the screen. The card speed is genuinely FAST as advertised. Low level formatting of the card allowed for very acceptable rapid-fire sequential still photo shooting speeds when light levels were bright enough that the flash was not needed/used. Something like 2 photos every 3 seconds. Files were flawless in display, both for stills and video.

This product was significantly lower in price than the Kingston 8GB SDHC card I originally bought with the camera. I've used both interchangeably and cannot see any different in the speed or capacity and quality of imagery is identical. For the money I'll stick with Transcend and am looking forward to getting their 16GB card once the price drops substantially below the $100 mark. That would provide nearly 2 1/2 hours of video on my still camera or 4600 highest quality stills. I'm afraid my camcorder will be collecting dust much of the time. A big advantage to video on the card is there are NO MOVING PARTS, e.g. a mini DV tape cassette and camcorder or VCR playback unit needed to dump the video and stills to my Mac for editing and burning DVDs. I just stick the card in the MicroMate USB card reader, plug it in the computer and bingo, ready to sort thru and dump to the hard drive. Since the card is formatted by a Canon camera it automatically boots up the Canon Viewer software too. That should work the same for other brands of still cameras formatting this chip.

The Fastest Card at This Price But..., June 26, 2007
This SDHC card is the fastest one in its price range but it may cause your images to be lost.

I use two of this in a Canon SD750. After the first use, all of the images were lost. (But thank God, I could rescue them with Lexar Image Rescue 2, a program better than its competitors) Then I formated the card(s) in the camera(s) with "low level format" option several times and there has been no problem after that so far.

I can suggest these points to potential owners of this card:
1- Use it very carefully, make backups if possible.
2- Format it several times before the first use with "low level format" option.
3- If you loose your images, don't panic. At this situation, It is very important not to take anymore pictures. If you take pictures after this point, you can overwrite your lost images and there can be no chance to get them back. Connect your card to your computer with a card reader (SDHC Compatible) and rescue them with Lexar Image Rescue.

Excellent Mini Hard Drive equivalent, December 11, 2007
This card is able to hold a complete DVD movie, thousands of songs/photos, or just serve as a backup device for one's files.

It operates very well - I now have purchased 3 and with each use its value becomes more apparent.

One word of caution - even though most laptops and systems have an SD card slot, older computers may not be able to recognize or write to this card. Make sure your system has the ability to read SDHC configured products.

If you do not have an SD slot you can purchase an tiny SD reader (very inexpensive) that plugs into your USB port.

Great value, just be careful..., January 2, 2009
It's great to have 8GB of memory but it is a double edged sword. Today after using this card for only the second time, it failed on me. I lost almost 200 precious images - gone forever. I am what you would call an enthusiast or hobbyist. I love photography and spend every spare minute, which is very seldom these days, pursuing my passion. So I do a fair amount of experimentation. These cards are great when they work - but if they fail you even once - the results can be catastrophic. Maybe I am the unlucky 1 of 250 reviewers with a bad experience with this product, but I feel it is my responsibility to report this to everyone. I hope it never happens to you. It is human nature for me to wonder, if I had spent a few more dollars for a better brand name, would my photos be intact today?

Great affordable SDHC card, March 28, 2008
In the past, I bought a Transcend 8GB SDHC card for my Canon SD1000 camera. I recently bought the Transcend 16GB SDHC for my new Canon SX20IS. Both cards work very well and I've had no problems with it so far. I wanted to take this opportunity to update my review since my original review was also posted (by Amazon) for the 16GB card. This is because the only difference between these two cards is the different capacity. So, if you're in the market for an affordable high quality SDHC card, this may be the one for you. Sorry, I kind of sounded like a used car salesman right there, didn't I? I assure you that I don't work for Transcend. But, here's why I think this card is awesome:

Pros:

-Affordable!

-Large capacity

-Class 6 read/write speed (which is very fast... but is no longer the fastest class available)

-Lifetime warranty (at least that's what the package says :)

-Transcend is a reputable company that's been making memory products for a very long time. ( I swear to the tech Gods that I don't work for them!) Other reputable and reliable memory card companies include Kingston and PNY. All three of these companies have been making memory chips for many, many years.


Cons:

- I can' really think of any "Cons" about this card. But here's the 2 closest things I can come up with right now: (1) "Class 6" is no longer the fastest speed available and (2) This card does NOT make coffee for you in the morning, do your dishes for you, give you compliments when you're having a bad day, or magically improve your photography skills.




IMPORTANT SPECIAL NOTES ABOUT SDHC MEMORY CARDS:

-SDHC cards are not compatible with most older SD cameras, SD devices, or SD card readers.

-SDHC cards are rated by speed using different "classes". There are currently 4 data transfer speed classes available for SDHC cards. These classes are "class 2, class 4, and class 6, and the new class 10. For example, "Class 2" would have the slowest read/write speed while "Class 6" has the fastest read/write speed. So if you have a device in which speed may play a crucial role, make sure you buy a higher "class" SDHC card. Please note that this SDHC card no longer has the fastest read/write speed available. There is now a new class, called "Class 10". Class 6 has a minimum read/write speed of 6MB/sec... while Class 2 has minimum speed rating of 2MB/sec, and Class 4 is 4MB/sec. Starting to see the pattern?


SO WHAT'S THE DIFFERENCE BETWEEN "SD CARDS" AND "SDHC CARDS?

SDHC is basically an upgrade to the older SD cards. The reason they upgraded it was to achieve greater data transfer speeds AND capacity than previously possible with normal SD cards... and to do this, they had to redesign the card (which is why it's not compatible with normal SD devices). This was necessary because digital cameras and digital video cameras these days have higher resolutions, which equate to larger file sizes and faster data transfer needs.

Now that many digital cameras also can record HD video, you may consider getting a larger capacity card because video takes much more space than photos. The size of the video varies from camera to camera depending on what resolution and video compression the camera uses. If you plan on taking lots of video (especially HD video), I would consider getting at least a 16GB card. Check your camera specifications to see how many minutes per Gig of memory your camera can capture ...to gauge how big of a memory card you'll want to get to meet your needs.

Special Note on regular SD Cards:
If you primarily take casual photos and don't need a exceptionally fast read/write capable card, you should know that newer cameras that take "SDHC" cards will also work with older normal "SD" cards. These older cards are cheaper than the new SDHC cards, so this may be something to consider. So to sum things up, newer cameras will take SDHC and regular SD cards, but older cameras that use SD cards may not be able to use SDHC cards. This is because newer technology is usually made to be compatible with older technology (the technical term used to describe this is "backwards compatibility") ... but older technology may not have the hardware necessary to run newer tech (technical term used is "obsolete"... just kidding! ;)

I hope I haven't confused everybody by going into this much detail, but I can't help being the nerd that I am. If you are confused, don't hesitate to comment on this post and I will try my best to answer your questions. Also, any feedback is always welcome!

Conclusion: Buy the card if you have a new device that uses SDHC. It rocks! (This message has been approved by the "Duke of New Mexico")

Transcend 4 GB Class 6 SDHC Card - Good Card for SDHC Compatible Devices, May 10, 2008
UPDATE - March 2, 2010: This review was originally written for the 4 GB class 6 SDHC card, but the reviews have been grouped for all class 6 SDHC cards in the 4, 8, 16 and 32 GB sizes. All the cards should perform similarly since they are all class 6 and all made by Transcend. However, I will have to check which cards I have used hands on. I believe I only own the 4GB and 8GB cards. I will update the review further. If you have concerns regarding the 16GB or 32GB sizes, you should seek out the reviews tagged with the product links from those cards.


The Transcend 4GB SDHC CARD (Class 6) is a great card for the price. I was at first a little skeptical about the brand, but I buy way too many memory cards to ignore a good price when I see one. And I'm happy to report that I've experienced decent performance and reliability issues with this card. That's as compared to other cards I own including SanDisk, PNY and Kingston.

As long as your devices are compatible with the SDHC format, this card is a good buy. 4 GB is a nice size though I do prefer 8 GB capacity for high capacity storage.

The class 6 speed is the fastest speed available in mass market SDHC cards. Class 6 guarantees minimum transfer speeds of 6 MBs, but I've gotten speeds up to 20Mbs! That makes this card perfect for storing pictures in RAW image formats.

The Class 6 speed is on par with the Sandisk Extreme III cards that on average are about $15 to $20 more per card. If you don't have an SDHC reader, you may opt to get the package with a reader included to download your pics. If not you can just transfer your pics directly from your camera with your card still inserted. An SDHC card reader can be bought separately if your PC doesn't have a compatible slot.

General SDHC and SD Card Tips

There are a few tips that I've learned the hard way through buying TOO MANY different memory cards.
1. Make sure your device is compatible with the card! Even in regular SD cards, some older electronics aren't compatible with that large of a size (2 GB). In terms of SDHC cards, make sure your camera or other device is SDHC compatible. SDHC is different from regular SD and only newer devices tend to have built-in compatibility
2. Once you install this in your camera or device, you will generally want to format the card with your compatible device's interface. That is because the standard formats for certain devices, particularly Canon, are different from the factory installed format
3. Just like your devices, most computer SD card readers are not compatible with the SDHC format. So use a card reader or download the pictures via USB connection to the camera with the card still installed.
4. For some reason, placing the card in the locked position allows some older laptops to still read it. This is just to be used in a pinch however, and it won't apply to all systems
5. If you did not properly format your card, you may be able to save things to it and then have them "disappear." If this happens to you, make sure you use the software recovery tools BEFORE you try to save anything else to your card. That way, you can retrieve your images without over-writing them.
6. Make sure you know what you are going to use this card for. Once you have set up everything and ensured it's all compatible, you still have to decide on speed. If you are using this for storing RAW images instead of JPEGs or HD video, step up to the faster class 6 speed format if you can afford it.
7. If you are going to pay more for a faster speed, make sure your device can benefit from it. I've read, for example, that Kodak cameras are set to a fixed voltage and cannot go faster than standard speed. So the extra cash spent on Class 4, 5, or 6 is basically wasted.

Conclusion

It's great to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card is worth it. Or you may want to step up to the larger 16 GB size that is now available.

Enjoy!

product failed., July 26, 2009
Well, it was great while it lasted. Unfortunately, it did not last long.

Like other reviewers, after <20 use cycles the device failed and I got a "lock" error when, in fact, the write-protection lock was not engaged. Oddly, by engaging the lock (i.e. entering read-only mode) I was able to remove the picture files from the card. Obviously, further use in the camera was impossible; I was also unable to reformat the card (either with my camera or with the SD Associations free software [..]).

This card has a high average rating but I would urge customers to consider the number of 1-star ratings due to complete product failure before they purchase this item.

My Canon loves the 8 GB SDHC card, January 15, 2008

I recently ordered this card as an accessory for my Acer Aspire One netbook PC. The card took a little while to ship, about 8 days, but that wasn't a big deal. The card has lots of space, and the read speeds are quite impressive. I mostly use it to run and store portable software, and it does a very good job at that.

My only complaint is that when I first inserted the card into my PC it attempted to install some adware. The program was from a company called RelevantKnowledge, and they gather your information for market research purposes. Luckily my spyware software picked it up immediately,so I was able to delete it. Afterward I formatted the card, and now I'm happy as can be.

I have 4 of these cards that I use in my Panasonic HMC-150, a professional grade video camera.

These cards are the best bang for your buck, and the frustration free packaging is awesome.
