Will the Sandisk Ultra, Class 6, 16gb, "20MB/s" card work for video on the 60D or T2i? Would the 8GB version be any different (more or less likely to work than the 16GB)?
According to SanDisk's own web site, the Ultra cards are class 4 speed, 15MB/s, not class 6 speed, 20MB/s. But I have seen some Ultra cards labeled class 6 for sale, with the same part number (SDSDRH-016G-A11). For example, B&H has a picture of a 16GB Ultra card with "20MB/s" and Class 6 symbol clearly shown, and the exact same part number as the class 4 card on SanDisk's site. I don't know what is up with that. Perhaps it is a new, future, re-labeled part that SanDisk doesn't show yet?
But it makes me suspicious, and I would suggest sticking to their Extreme line of cards, all of which are class 6 or faster. That's what those cameras need for their video (1080p @ 30fps).
