Lexar

Lexar SL100 Pro 2TB

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.
