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).

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.
