Transcend StoreJet 25 Mobile
Suffice it to say that the Transcend StoreJet 25 Mobile is tough as nails. As a matter of fact, Transcend describes it as "a cybernetic organism: living tissue over a metal endoskeleton." Alright, maybe they didn't go THAT far, but this little external hard drive can take a free-fall drop or two, for sure.
It's built with three layers of material protection from the elements: a durable silicone shell, a suspension bracket, and a thick rubber casing on the outside. While we don't recommend you use this hard drive for artillery, it's certainly strong enough to withstand daily travel to and from the workplace.
