Our Pick

Corsair

Corsair EX100U Portable 2TB

A 2TB Gen 2x2 portable with the Corsair aluminum body. Write speed drops to 1800 MB/s over the 1TB 2000 - a 10% bump down for the larger die stack. Still above 2GB/s on paper for long transfers as long as the host is Gen 2x2.

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.
