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.

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.
