I'm looking for an external drive ~$100, ~320 GB, that's bus powered so I can take it with me wherever I go without having to plug it into an outlet. I basically need it just to consolidate my (very large) music collection which is spread across 3 different drives at the moment so I can have it all with me. Which company right now is making the best sub-$100 drives and are the most reliable? Difference between reliability when it comes to 500 GB, 320 GB etc.?
In terms of brand, Seagate, Western Digital, LaCie, etc.; one isn't necessarily better than the other?
