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.

Netac

Netac ZX1 Portable 1TB
7.5/10

A budget Gen 2x2 portable from Netac -- aggressive price vs the brand-name tier. The 1800 MB/s write rating is real but drops further on sustained workloads past the SLC cache. A valid budget pick for game-library overflow where peak sustained write does not matter.
