Is this ok for my 60D or should I get something like a class 10 Sandisk with a write speed of around 45MB/s. I really don't do a lot of burst shots, but I do video and stills. Your video stream is 5.5MB/sec, so your card should be fine. Tom

For photos class 6 is plenty fine. If you shoot 720 video, you'll probably never have and issue. If you shoot 1080 then you could possibly run into problems with video stopping recording for write speeds, but you'll only know by shooting some test footage (let it run recording and see if it stops for write speed or stops on its own at the 10-12min cutoff) My junk

Class 6 is spec'ed handle 6 MB/s sustained write. As I said above, the video bit stream (even 1080p) on his 60D is 5.5 MB/s max. Tom
