Designed for 2.5″ hard drives—that’s notebook hard drives—the shockproof casing protects drives up to 120cm (3.9 feet). That’s just about the distance between your desk and the floor, or your hands and the floor. The sides are made of plastic and provide cushioning for falls, at least if it lands on the bumper. Inside is coated with foam to pad the hard drive itself. We just hope this foam isn’t combustible, as hard drives can get pretty darn hot.
