The case seems to me to be a little edgy. Otherwise, a simple no-frills external hard drive. Use this for external fuses (not continuous operation). Connecting, works. Bin with the speed over USB 3.0 as measured by HD Tune 2:55 min 50 MB / sec, Max: 108 MB / sec, Avg: 86 MB / sec. extremely satisfied. If times lukewarm in operation.
