but usb 2.0 is a little better than firewire 400
USB 2.0 has a higher max data transfer rate of 480 mb, but has to be routed through the cpu and and any speed is completely dependent on the motherboard, cpu and all the processes the computer is handling. Firewire doesn't have to route through the CPU first and the data transfer rate is independent of any other things going on. Also, the max speed of 480 for usb 2.0 can't be sustained for long periods while firewire's 400 mb transfer rate can. So, firewire 400 is actually better.
