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.

Transcend

Transcend ESD310C Portable 1TB
7.6/10

A tiny 1050-class Gen 2 portable from a long-established memory brand. The ESD310C is among the smallest 1TB Gen 2 SSDs in retail -- small enough to be lost in a bag. Buy it for the form factor over sustained performance.
