Crucial

Crucial X6 2TB
8.0/10

The 2TB X6 is a budget buy for console-game storage or backup duty — at 800 MB/s it's easily fast enough for cold-game library overflow on PS5 (where the internal SSD handles active play), and the larger die stack holds the 800 MB/s rate longer than the 1TB.

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.
