i dont have the DVD and as mentioned i dont even use firewire no point when USB is faster the DVD was borrowed and its costs more than Windows 7 to get a copy!!!!
USB 2 has a faster thericical speed. But FireWire 400 has a faster real world speed. USB 2 tops out at about 35 megabytes per second. FireWire 400 is about 45 megabytes per second with lower latency. And don't forget if the USB host is running low on free CPU cycles, USB speeds suffer because USB is CPU dependent, unlike FireWire whose chipset doesn't need CPU cycles. That's why FireWire is what provides Target Disc Mode.
