Our Pick

LaCie

LaCie Rugged SSD 1TB

8.6/10

The non-Pro Rugged SSD keeps the IP67 orange-rubber body but drops the Thunderbolt controller for USB 3.2 Gen 2. For photographers and documentarians whose laptops don't have Thunderbolt anyway, this is the right compromise at a much lower price than the Pro.

Lexar

Lexar SL100 Pro 1TB

7.5/10

A 950 MB/s Gen 2 portable in a brushed-aluminum case the size of a credit card. The SL100 Pro is one of the smallest 1TB Gen 2 SSDs at retail — buy it for the form factor, not the rated speed (which undershoots the Gen 2 ceiling).
