If you need a fast, portable SSD that can withstand life on the road, the CalDigit Tuff nano is an ideal choice.

CalDigit, a popular provider of PC accessories including our pick for a Thunderbolt 3 docking station, has released a miniature version of its Tuff solid-state drive (SSD). The Tuff nano is advertised as a small, durable SSD that brings impressive performance, ideal for popping into a pocket or laptop bag when you hit the road. I gave the Tuff nano a week of use to see what it's all about and whether or not it's worth your time.
