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.

Sabrent Rocket XTRM-Q 2TB

8.6/10

The 2TB XTRM-Q is the model that put Sabrent's portable Thunderbolt line on the map for Mac users who needed internal-class speeds in an external chassis. Like the 1TB, it dedicated to Thunderbolt 3/4 hosts — on USB only you'll see Gen 2 speed (~1050 MB/s), not the headline 2700 MB/s.
