I've been using a 20Gb external drive for at least a year with no
problem - the one I have is a small unit (laptop hard disk) and has both
USB and firewire. I got around 12 MB / second out of it (firewire),
limited by the disk last time I checked.

Firewire support has been very flakey at times in the 2.4.x kernels, but
now works pretty well provided you don't let your laptop go to sleep (: 

If you have to fall back to USB of the first version, it'll be slow, as
you say, but for archiving that won't matter.
