Our Pick

Crucial

Crucial X9 Pro 1TB

9.0/10

A 1050 MB/s portable SSD for creators who need TLC NAND, hardware encryption, and a 5-year warranty at less than Extreme Pro prices. The X9 Pro is Crucial's premium Gen 2 line — it targets direct-edit workflows where sustained writes and write endurance matter more than headline speeds.

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.
