Our Pick

LaCie

LaCie Rugged SSD Pro Portable 4TB
9.2/10

A 4TB Thunderbolt 3 portable in the iconic LaCie rugged orange body - one-of-one at this capacity/speed tier. Largely without competitor at 4TB Thunderbolt 3 + IP67 = niche product, premium pricing pairs the niche.

Netac

Netac ZX1 Portable 1TB
7.5/10

A budget Gen 2x2 portable from Netac -- aggressive price vs the brand-name tier. The 1800 MB/s write rating is real but drops further on sustained workloads past the SLC cache. A valid budget pick for game-library overflow where peak sustained write does not matter.
