I just read that USB 2 can handle 480Mb/sec whereas firewire can only do 400Mb/sec. Is this true??? I am asking because I have one of those DVD burners that uses either Firewire or USB 2 and I figured I'd get better/faster performance by adding a firewire card instead of using the USB. Is there any reason (because the speed doesn't seem to be an issue now) why I would use the firewire port over the USB 2 port? Or is this a non-issue?
