As I'm looking at acquiring a new system for Vegas someone pointed out that I shoud be sure and get a motherboard with USB 3.0 ability.
(FYI, so far I have only been able to find motherboards with 2 of the USB ports USB 3.0 while the other USB ports on the board are USB 2.0. Of course you can add a USB 3.0 card.)
Anyway I thought this YouTube review video clearly showed the difference between USB 2.0 and USB 3.0.
It is probably old news for most now but maybe some will find it informative.
