LaCie

LaCie Rugged SSD Portable 1TB
8.6/10

The Rugged SSD without the Pro - same IP67 orange body but USB-C Gen 2 instead of Thunderbolt. The right compromise for photographers and documentarians whose laptops do not have Thunderbolt anyway and want the ruggedization at a more reasonable price.

Our Pick

OWC

OWC Envoy Pro FX Portable 4TB
8.9/10

4TB of Thunderbolt 3 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 6K/8K video editing workflows where sustained 2800 MB/s transfers plus 4TB of room actually matter.
