I recently purchased a JVC GY-HM100U camcorder, which requires a class 6 SDHC card. I purchased five of the Centon class 6 cards to use in my camera. The camera does a speed check on the card to make sure it can handle high data rates.

They did not work. With the exception of one of the five cards, all of the rest were rejected by the camera as being too slow. These cards do not, for the most part, achieve class 6 speeds.

Just dropped this in to my Canon T2i -- I'm usually able to snap off about 20 shots at full speed with 18mpx photos on a decent 16gb class 4. I was consistently only able to get off 12 before the buffer was full and it started to drag with the Centon. I just benchmarked my card in XBench and my class 4 card scored a 1.69 which is expected for a class 4 card. The Centon on the other hand scored a paltry 0.90 -- pretty sad really that the class 4 scored almost twice as high.

Sustained write speeds on this card are only ~6.3 MB/s with a 4k block size. To give you an idea of how slow that is, the T2i can shoot 3.7fps continuous... at 18mpx that's 28MB/s that need to be written out to the card.

Don't use this card for anything you need actual class 6 speeds (sports/action photography or video). Would be fine for a point and shoot though (which is where mine is headed).

Works fine in my camera been using for a few months now. Wish i had waited and got the 32GB as that is the same price now as I paid for the 16GB a few months back.

Do not buy this card, it's very unreliable. It would even give write errors on my Panasonic point and shot camera.

I was ready to throw it to the garbage because it never really worked right. When using this card most of the pictures came half green or black (literally due to presumably write errors) on three different cameras (Canon, Panasonic and Kodak).

Then I thought I could give it a try and format it using Lexar Image Rescue 4... The utility took about 45 minutes to format the card, and after that it "kind of works" OK unless I shoot many frames rapidly *not even in burst mode* (otherwise it gives bad *unreadable* frames). Please note that I'd formatted the card many times before using the camera and the PC, the only thing that worked was Image Rescue 4.

It's not only that this card is very slow, because if so, it would just take longer to write the images to the card. The weird thing is that it "kind of works" OK only on my DSLR but not on my point and shoots. It doesn't make a difference if I shoot small JPG or large RAW files.
