I've just moved to Uni, and left the 2.5TB desktop at home (with its crap internet connection) so can't store stuff on that, so I'm looking for something 500GB+ for my parents to buy me for Christmas. 2.5inch, so I can power it off USB 2.0 preferably. Anyone have a really awesome one that they'd recommend? Or do I just grab the cheapest? I'm not after backup software, just storage space.
