Our Pick

Corsair

Corsair EX100U 2TB
8.5/10

A 2TB Gen 2x2 portable SSD in the same aluminum-and-rubber body as the 1TB. Write speed drops slightly to 1800 MB/s on the 2TB variant — a real-world trade-off for the larger NAND die. Still above 2GB/s on long transfers as long as the host is Gen 2x2.

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.
