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.

Seagate

Seagate One Touch SSD Portable 1TB
7.7/10

A 1TB budget portable from Seagate — typically the lowest-priced 1TB brand-name Gen 2 portable SSD available. Comes with the Resident Rescue data-recovery plan, which is meaningful coverage at a price point where the drive is seen as disposable.
