Our Pick

Crucial

Crucial X10 Pro 2TB
9.5/10

The 2TB X10 Pro takes advantage of Gen 2x2 hosts but falls back gracefully on Gen 2 to 10 Gbps. A safe long-horizon buy — even if your current laptop only has Gen 2, you'll see 2000 MB/s the day you upgrade to a Gen 2x2 host. Same TLC NAND, 5-year warranty, and encryption as the X9 Pro.

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.
