The Armor A80 is the first device from Silicon Power I've seen, and it's impressive. The drive is waterproof, rugged, and most importantly very fast, according to my testing. Despite all that, it still manages to be as compact as other portable drives that are based on 2.5-inch standard internal hard drives. It's also bus-powered.
The Good
The Bad
The Bottom Line
The only shortcoming the A80 has, if any, is that it uses A-male-to-A-male USB cable, which is harder to run across than regular A-male-to-B-male USB cable. To make up for this, the drive comes with two cables, one of which is short enough to tuck inside a groove on the drive's side.
If you can live with this odd choice of the USB cable, at a street price of around $135 for 1TB, Silicon Power's Armor A80 makes an excellent portable hard drive to use on the go or at home.
