Our Pick

Crucial

Crucial X6 Portable 4TB
8.0/10

A 4TB portable at the X6's budget price is closer to spinning-rust economics than SSD. The 800 MB/s ceiling doesn't matter for the use case — the entire point is capacious portable cold library overflow for PS5, Xbox, or photo archive, not peak throughput.

Silicon Power

Silicon Power PC60 Portable 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.
