Our Pick

OWC

OWC Envoy Pro FX Portable 4TB
8.9/10

4TB of Thunderbolt 3 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 6K/8K video editing workflows where sustained 2800 MB/s transfers plus 4TB of room actually matter.

Western Digital

WD Black P50 Game Drive SSD Portable 2TB
8.6/10

The 2TB Black P50 doubles the SLC cache budget of the 1TB — sustained writes hold 2000 MB/s noticeably longer than on the 1TB. RGB-free Gen 2x2 with a 5-year warranty is genuinely rare; the chief competitor is the Kingston XS2000 2TB, also 5-year but lower price.
