I've been looking for an external solution for my xps2 laptop, it's 7200rpm drive is fast enough but with only 60gigs I'm out of room with all of the games I play. I have an external 120gb 3.5" enclosure connected thru firewire which works well enough, but I'm wanting something that is a little smaller and is totally powered by one or two USB ports...capacity needs to be at least 100gb and a firewire connection would be a big plus, can anybody recommend a drive??
