Corsair

9.0/10

A 1TB USB4 portable — 3300 MB/s read on a Thunderbolt 4 / USB4 host. The EX400U is the rare USB4 drive that supports the full 40Gbps link (not all USB4 drives do). 5-year warranty is best-in-class for the speed tier.

WD Black P50 Game Drive SSD 1TB
8.5/10

The WD Black P50 was the first console-targeted portable SSD to claim Gen 2x2 speeds on paper, although on a Gen 2 host it caps at 10Gbps. Big in Xbox/PS5 circles for the gamer-aesthetic naming and the 5-year warranty.
