If you're out in the market looking for a high-capacity 2.5" rugged portable hard drive that isn't lacking in performance then the latest Armor A62 line by Silicon Power is certainly worth checking out.

Just like the rest of the Armor line of PHD's the A62 model features a rugged IPX4 water and scratch resistant enclosure (made out of hard plastic this time over) which is also shockproof certified (via an internal suspension system) for drops from up to a height of 122cm (USA military transportation test - procedure IV). Silicon Power actually makes two A62 PHD's currently the slim (14.9mm - uses 7mm drives) A62S model available in 1/2TB capacities and the "thicker" (22.8mm - 15mm drives) A62L which is available in 2/3/4/5TB capacities. Inside the USB 3.1 Gen 1 compatible enclosure of the A62L 4TB model Silicon Power has placed a WD Blue Mobile SATA III 2.5" 15mm thick drive (WD40NPZZ model) which spins at 5400RPM (features WD's IntelliSata and IntelliPower Technologies) and is equipped with 8MB of cache.
