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.

Lexar

Lexar SL100 Pro Portable 1TB
7.5/10

A brushed-aluminum portable SSD the size of a credit card -- one of the smallest 1TB Gen 2 SSDs in retail. Buy it for the form factor; the 950 MB/s rating undershoots the full 1050 Gen 2 ceiling.
