Flash-based external direct-attached storage (DAS) devices have evolved rapidly over the last few years. Starting with simple thumb drives that could barely saturate USB 2.0 bandwidth, we now see high-performance external SSDs.

It caters to the mainstream market and comes in three capacities – 256GB, 512GB, and 1TB.In this review, we take a look at the 1TB version.
