LaCie Rugged SSD 1TB vs OWC Envoy Pro FX 4TB

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.

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.
