There’s a hidden part of each of us that revels in destruction. That part of us sees a piece of technology billed as “rugged” and vows to destroy it. Granted, most rugged hard drive enclosures are a joke—a thin layer of rubber over a standard plastic chassis; or a thin aluminum shell, if you’re lucky, with a 2.5-inch drive held inside. They’re meant to survive a drop from a desk to the floor, or sometimes just to look . IoSafe, on the other hand, is serious about the “rugged” label, and the Rugged Portable SSD is among the toughest external drives you can get.
