Our Pick

Lexar

Lexar SL100 Pro 2TB

7.6/10

The 2TB SL100 Pro keeps 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 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.
