Our Pick

OWC

OWC Envoy Pro FX 4TB
8.9/10

4TB of Thunderbolt 3 storage in an aluminum unibody barely larger than the 1TB. The Envoy Pro FX 4TB is a niche-of-one — buyers typically pay the premium for video editing workflows where 4000 MB/s sustained links plus 4TB of room actually matter.

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.
