The A-DATA SH93 hard drive looks to be covered in caution tape, but you needn't worry about dropping it on land or water.
Both shock and
sea bath-proof (to depths of a modest one meter for 30 minutes at a time), the rubber-coated SH93 protects up to 640GB of files through your stupidest (or clumsiest) adventures. Still, the most handy feature might not have to do with its toughness: The drive's wrap-around USB cord means that, typhoon or mudslide, you won't be fumbling around for the wire. (Then again, your business-class laptop will be destroyed anyway.)
