Our Pick

The 2TB XS2000 is a budget-grade Gen 2x2 portable with the same 5-year warranty as the 1TB but double the cache budget. Often the cheapest 2TB Gen 2x2 SSD at retail — a sensible budget alternative to the Sabrent or Samsung T9.

Lexar

Lexar SL100 Pro 1TB
7.5/10

A 950 MB/s Gen 2 portable in a brushed-aluminum case the size of a credit card. The SL100 Pro is one of the smallest 1TB Gen 2 SSDs at retail — buy it for the form factor, not the rated speed (which undershoots the Gen 2 ceiling).
