Bits and BytesDec 06, 2009
By Rob Regarding complaints about performance with HD camcorders:
SDHC cards are rated in MegaBytes per second (MB/sec). HD camcorders are rated in Megabits per second (Mb/sec). There are 8 bits per Byte.
Therefore, an HD camcorder with 24Mb/sec video capture requires (24Mb/sec) / (8Mb/MB) = 3MB/sec SDHC card. A Class 4 SDHC card with at least 4MB/sec data transfer is more than enough to capture full HD. Those camcorders are not designed to work with Class 6 and Class 10 cards.
Remember that Full HD, 1920 x 1080 pixels = 2,073,600 pixels, or 2 Megapixels. Digital SLRs shoot at 12 Megapixels with minimal lag time between shots requiring much higher data transfer rates than HD camcorders.
Consequently, people who use Extreme Class 10 SDHC cards with high speed digital SLRs seem happy, but people using them with HD camcorders are not. It can be confusing, but you must use the appropriate card for your application. Faster is not always better.

So far so goodAug 21, 2009
By Mauricio G. Villablanca I put this baby to the test on a Nikon D90 in burst mode. The amazing performance of this memory card allowed the camera to keep using its buffer taking pictures at 4 frames per second for a period of at least 30 seconds (excellent lighting conditions). Hear the machine gun in your ear as you take your pictures at a sports event or at SeaWorld while dolphins jump out of the water and get a shot worth being published on Sports Illustrated. Wow!
With its huge capacity, you will probably never need to carry another stick in your camera bag. I set the resolution at the highest level on the D90 and the indicator showed I could store 2,100 pictures in this memory card. Awesome!
Very good purchase, the price is high, true but the name says it all about its performance: "EXTREME".

This memory keeps up with a fast cameraNov 02, 2009
By Keith Barnes A fast camera needs a fast memory chip.
Highly recommended for taking multiple shots. Pay attention to the memory class.
I use a Nikon D90 at my grandchildrens's soccer games. The camera is set to high repeat, so when the ball lands near my grandchild, I push and hold the shutter button for about ten shots. I usually get two shots that show the ball and my subject with nobody in front. The class 4 chip (class indicates speed) I was using would pause the shooting because the camera's temporary memory was full. With this class 10 memory chip, the shooting is uninterrupted. The memory seems to operate at camera speed.

Lets SLR Camera perform at its bestJul 13, 2010

I purchased this disk along with a Canon EOS Rebel T2i Canon EOS Rebel T2i 18 MP CMOS APS-C Digital SLR Camera with 3.0-Inch LCD (Body Only) about two weeks ago. I was very happy with the performance of the camera. I shot a swim meet and some other sports activities and got some great shots, especially on continuous burst. The next day I inadvertently left the Class 10 card at home, and had to substitute a Class 6 card.
The difference in the performance of the camera was remarkable. The camera took longer to start up, the speed of taking photos on continuous burst was much slower, and after about 10 frames the camera slowed to a crawl. As a result, I ordered another Sandisk Extreme Class 10 card as a backup.

Quick card (tested with Canon T2i rebel)May 03, 2010
By eSurfer

Quick card. 1080 video shoots without interruption and 3 jpg/second (18 megapixel) continuous shooting (Canon Rebel T2i). Works as expected. Shooting 1080 video, sorta wished the card was higher capacity. 3 minutes fills a gig of space. So, (Canon Rebel T2i) about 4 12-minute clips.
