Does not perform at 20MB/sec, 2010-03-22
It does not perform much faster than a normal 4 GB card. Since it is three times the cost, it is not worth it. I use several SD cards for photography and it is not much better/faster than a cheaper card, it was about a 1/10th of a second faster than my cheaper cards. This quote from Amazons product page "Fast 20MB/sec sequential Read/Write speeds" is not accurate, it never performed faster than 6MB/sec. I did several speed read/write test on it and it performed at just its rating as a C6 card (6MB/sec), and just barely faster than a SanDisk C2 card. If your are being drawn in with its published "super speeds" and hoping to increase you cameras picture speeds like I was, you may be disapointed like I was. I find that having good high current batteries makes a much bigger difference. I have come to believe that Kingston is a better purchase over any Sandisk product. SanDisk customer support is very poor.
Great photo card, 2009-01-20
I bought this photo card for my Canon SD 1100 is.
I am very happy with the card. I test the card against a regular SD card and there was little differance but the Extreme III was Slightly faster
