I think I may go with USB because this thing is strickly going to be a back up (no streaming)... and I use USB to load my songs on the empeg anyway, so I'm a bit used to it. Also, I found one that supports USB2... I don't have USB2 on my notebook, but this will expand the possibilities.

Here is what I found. $220 for a 80GB 5400rpm drive. I imagine that upgrading the drive won't be too hard either. They sell 7200rpm models.. but with USB, what's the point? The specs mention something about Firewire, but I think that is a typo.

Comments?
