I'm about to purchase a Canon D7. I have a question in relation to the CF memory card. Checking out various brand specs and I note that basically for a given gb storage the rated speed is the determining factor in price.

Given that the D7 specs indicate about 8 fps, obviously the faster rated memory cards the better. From what I can gather there are three speed rated cards, 30, 60 & 90 mb/sec. I'm looking at a 32 gb card but the price for the 90 mb/sec model is rather expensive but am not shying away from the price of the 60 mb/sec card.

So, is a 60 mb/sec CF memory card more than adequate for a D7? If my calculations are correct, shooting only JPEG images, each apprx 6.5 mb, equates to (60/6.5 = ) 9.2 fps (not that the D7 will achieve that).

Are there any other factors at play?
