Our Pick

SanDisk

SanDisk Extreme Portable 1TB
8.5/10

The non-Pro Extreme is the lower-cost sibling — same 1050 MB/s rated read and IP55 rugged body, but writes top out well below Extreme Pro on sustained workloads. A solid buy when the write-speed gap doesn't matter (game consoles, file transfer, backup) but the rugged rating does.

Cheaper than Pro by a wide margin

Silicon Power

Silicon Power PC60 2TB
7.4/10

A 2TB budget Gen 2 portable aimed at game-library cold storage for PS5/Xbox. Aggressive pricing makes it competitive against the Seagate One Touch 2TB on sale. Not a drive for sustained-write-heavy creative workflows.
