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

Seagate

Seagate One Touch SSD 2TB
7.8/10

The 2TB One Touch is the sweet spot of Seagate's budget portable line — large enough die stack that the sustained-write dropoff after SLC exhaustion is significantly longer than on the 1TB.
