You could probably get something with a little more space if you need it at the expense of the drive being physically bigger and having to use a power cord. Personally i like not having to haul around a cord if i bring my external over to my friends house, but if your just using it for backup it may not apply to you.I would get a WD passport for that price range, you can get a 500GB one for $100, and its a 2.5" HDD so no power cord just USB, and its small.
