8. Silicon Power 1TB Rugged Armor A60 Military-grade Shockproof/Water-Resistant External Hard Drive
Price on Amazon: $57.99
1TB in an 8-ounce package, you have to admit that’s pretty dense. A 2TB version will set you back $108, so it’s beyond the scope of this list. The manufacturer claims that the drive is built to military specs, so it should be able to withstand occasional bump.
