Lexar

Lexar SL100 Pro 1TB
7.5/10

A 950 MB/s Gen 2 portable in a brushed-aluminum case the size of a credit card. The SL100 Pro is one of the smallest 1TB Gen 2 SSDs at retail — buy it for the form factor, not the rated speed (which undershoots the Gen 2 ceiling).

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.
