8.5/10

A 2TB Gen 2x2 portable SSD in the same aluminum-and-rubber body as the 1TB. Write speed drops slightly to 1800 MB/s on the 2TB variant — a real-world trade-off for the larger NAND die. Still above 2GB/s on long transfers as long as the host is Gen 2x2.

LaCie

LaCie Rugged SSD 1TB
8.6/10

The non-Pro Rugged SSD keeps the IP67 orange-rubber body but drops the Thunderbolt controller for USB 3.2 Gen 2. For photographers and documentarians whose laptops don't have Thunderbolt anyway, this is the right compromise at a much lower price than the Pro.
