Our Pick

Crucial

Crucial X9 Pro Portable 2TB
9.0/10

The 2TB X9 Pro doubles the cache budget over the 1TB. Real TLC NAND and 5-year warranty gives Crucial's premium portable line a longer-lived write endurance than consumer QLC alternatives. The right buy for editors who want a working drive rather than a backup drive.

Lexar

Lexar SL100 Pro Portable 2TB
7.6/10

The 2TB SL100 Pro in 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.
