The one thing that was never mentioned in what Quig posted was about the class. The class ONLY determines the write speed. Really only noticed when writing large files to the card. It does not affect the read speed at all. So once the card is filled it doesnt matter what class it is as it will still read the same. So do not think you are getting better performance with your videos from a class 6 card than a class 2 card.
Hm i didn't know that. But even so, when loading an album, HTC Album creates the cache and thumbnails on the spot, and mine is saved on the SD card, and the write speed could help there. I could also think about situations where programs that stream stuff put the buffer on the sd card. Anyway, so far i haven't seen class 6 16 gb cards on the market. I'm still looking.
