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.
