I doubt you will see any difference in the 7000. In fact there are only a few professional digital slr cameras where you might see a difference when taking sequential raw shots and filling the buffer completely. Most interfaces are too slow to take advantage of the full speed. You will see a difference only in transferring very large numbers of very big files to computer, and then not through a usb 1.1 interface, you'll need a usb2 or firewire interface.

I've tested different SD cards with a virtual 5:1 speed difference in laptop transfer, and when saving and loading on the 7000 you can hardly tell any difference (this includes audio transfer) because the files are so relatively small.
