If you are into portable USB backup hard drives but need the ability to withstand a 300 g shock (hey, you’re rough, right?) then look no further than the CMS ABSmini Backup System. The drives spin at 4200 rpm so they are not the fastest you can find but there are certainly none tougher. The CMS drives have a one button backup function ensuring your portable PC will stay safely backed up in the event of real trouble. The drives are available in 20, 40, and 60 GB capacities for $179, $259, and $329, respectively.
