Move Speed WD 05
Score: 50/100Rankings

Buffalo's 1 TB SSD-PUT is a thumb-drive-sized external SSD that delivers solid 600 MB/s read performance in a rugged, MIL-STD-810G package, though it needs a firmware update and uses an adapter for USB-C connectivity.

The MOVE SPEED 256 GB SSD blends decent USB 3.2 Gen 1 performance with biometric AES-256 encryption and a sturdy zinc-alloy body. It shines for security-focused mobile users, though its capacity and speed are modest and it lacks an IP rating.
