Our Pick

Lexar

Lexar SL660 Portable 1TB

8.1/10

A 1TB Gen 2x2 portable with an aluminum body and an RGB-lit Logo -- the RGB is divisive but the performance is real. Build quality distinguishes the SL660 from cheaper Gen 2x2 peers like the Patriot Evlvr.

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.
