Our Pick

Corsair

Corsair EX400U 1TB

9.0/10

A 1TB USB4 portable — 3300 MB/s read on a Thunderbolt 4 / USB4 host. The EX400U is the rare USB4 drive that supports the full 40Gbps link (not all USB4 drives do). 5-year warranty is best-in-class for the speed tier.

Netac

Netac ZX1 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 doesn't matter.
