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.

LaCie

LaCie Rugged SSD Portable 1TB
8.6/10

The Rugged SSD without the Pro - same IP67 orange body but USB-C Gen 2 instead of Thunderbolt. The right compromise for photographers and documentarians whose laptops do not have Thunderbolt anyway and want the ruggedization at a more reasonable price.
