Crucial

Crucial X6 4TB

8.2/10

A 4TB external at the X6's price is closer to spinning-rust economics than to typical SSD pricing. The 800 MB/s cap doesn't matter when the use case is video archive or photo-library cold storage — this drive is bought for capacity first, speed second.

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.
