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.

Seagate

Seagate One Touch SSD Portable 2TB
7.8/10
