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 2TB
7.6/10

The 2TB ZX1 doubles both capacity and SLC cache budget. Budget pricing holds -- among the most affordable 2TB Gen 2x2 portables at retail. Buyers should temper expectations on sustained writes after the SLC cache exhausts.
