Our Pick

LaCie

LaCie Rugged SSD Pro 2TB
9.1/10

The 2TB Rugged SSD Pro doubles capacity of the iconic Thunderbolt 3 rugged drive. The standard field drive for outdoor wedding, extreme-sports, and news videographers who need both real-time 6K editing and a drive that survives a sandstorm.

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.
