External USB hard drives provide a quick and easy way to add storage space to a computer without the need to ferret around in the case, with the added bonus that they're easy to move from one computer to another.

Losing data is bad enough – especially if you've misplaced photos or precious documents – but its potential use if it fell into the wrong hands hardly bears thinking about.
