Our Pick

Lexar

Lexar SL100 Pro Portable 2TB
7.6/10

The 2TB SL100 Pro in the same brushed-aluminum credit-card footprint of the 1TB. Famously pocketable but only marginally faster on sustained writes thanks to the larger SLC cache.

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.
