Some crude, subjective figures (dragging and dropping file with an eye
on the Date/Time Control Panel applet) from transferring a 677MB disk

Epox 8RDA+ (2GHz Athlon XP 2400+):

USB 2.0:  63s average
Firewire: 35s average
USB 1.x: gave up, but WinXP estimated 12minutes (via hub built in to
Iiyama monitor).

IBM ThinkPad A30 (1GHz PIIIm):

IBM Cardbus Firewire adapter: 70s average

Epox 8RDA+ (2GHz Athlon XP 2400+):

USB 2.0:  63s average
Firewire: 35s average
USB 1.x: gave up whilst falling about laughing as WinXP estimated 12
minutes (via hub built into Iiyama monitor).

IBM ThinkPad A30 (1GHz PIIIm):

IBM Cardbus Firewire adapter: 70s average
USB 1.x: didn't even bother - see Epox result above.
