Well yes, a class 6 will work fine but a class 10 (20MB/s) or a SanDisk rated at 30MB/s works better. At least on my K10D it does.

"Better" in what sense?

Better in the sense that if the write speed is higher (it is) the limited buffer in the DSLR is emptied faster and is then freed up to allow the next image from the image processor. Standard queuing type considerations - just like in a disk drive or tape drive on your computer (yes big server computers use tape drives - don't get me started).

But is this noticeable in actual use?
