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.
