A Thunderbolt 3 portable SSD in LaCie's iconic orange-rubber bumpers — IP67, 3-meter drop, and 1-ton car-proof. The Rugged SSD Pro is the field-shoot standard for video crews who need one drive that survives a van rollover and still delivers Thunderbolt-class 2700 MB/s.

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).
