I want to buy a 2 GB Memory Stick Pro Duo for my Sony DSC w7
7.2megapixel camera.

There are basically 2 types of these sticks 1 is "high speed" (80mbps)

and the other is normal speed (15mbps). They say this is read/write
speed or something.


Now the basis of my question is - Does the high speed improve the
performance of my camera or is it simply the transfer rate from the
memory stick to my computer?
Thanks for any help you can give!
