Crucial X6 1TB vs Lexar SL100 Pro 1TB — Which External SSD Is Faster & Better Value?

Our Pick

Crucial

Crucial X6 1TB

7.8/10

The X6 is Crucial's budget Gen 2 line — half the speed of the X9 Pro at typically half the price. A sensible choice for game-library expansion on PS5/Xbox or as a Time Machine drive, where sustained write speed matters far less than capacity-per-dollar.

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).
