Our Pick

Crucial

Crucial X10 Pro 2TB

9.5/10

The 2TB X10 Pro takes advantage of Gen 2x2 hosts but falls back gracefully on Gen 2 to 10 Gbps. A safe long-horizon buy — even if your current laptop only has Gen 2, you'll see 2000 MB/s the day you upgrade to a Gen 2x2 host. Same TLC NAND, 5-year warranty, and encryption as the X9 Pro.

Lexar

Lexar SL660 1TB

8.1/10

A premium 2000 MB/s Gen 2x2 portable with an aluminum body and an RGB-lit Logo. The RGB is a divisive feature but the performance is real, and the build quality distinguishes it from cheaper Gen 2x2 peers like the Patriot Evlvr.
