Our Pick

OWC

OWC Envoy Pro FX 2TB
8.8/10

The 2TB Envoy Pro FX keeps the same small unibody of the 1TB but scales the die stack. The sustained write behavior on the 2TB stays pegged at 2800 MB/s well past 500GB on a Thunderbolt 3 host.

SanDisk

SanDisk Extreme Portable 1TB
8.5/10

The non-Pro Extreme is the lower-cost sibling — same 1050 MB/s rated read and IP55 rugged body, but writes top out well below Extreme Pro on sustained workloads. A solid buy when the write-speed gap doesn't matter (game consoles, file transfer, backup) but the rugged rating does.
