Our Pick

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.

Seagate

Seagate One Touch SSD 2TB
7.8/10

The 2TB One Touch is the sweet spot of Seagate's budget portable line — large enough die stack that the sustained-write dropoff after SLC exhaustion is significantly longer than on the 1TB.
