I just bought a Lexar Platinum II class 6 card, 32Gb to hold lots of RAW and some video files. SD cards are small and I'd likely not be swapping them out as much as I do with my 5D (8gb CF cards are the biggest I have). Is class 6 adequate for video (seems to look like it on the box) or would I be better off to return it and get a class 10? I won't be doing a TON of video, this is for a S100 afterall not a 5DmkII or something. I paid $45 (Canadian price) for the 32gb.
