Crucial X6 1TB vs Crucial X6 4TB

Compare Crucial X6 1TB and Crucial X6 4TB side by side. Both are 1TB USB 3.2 Gen 2 external SSDs, but they differ in speed, design, and value. Here's how they stack up.

Crucial

Crucial X6 1TB
7.8/10

The X6 is Crucial's budget Gen 2 line — half the speed of the X9 Pro at typically half the price. A sensible choice for game-library expansion on PS5/Xbox or as a Time Machine drive, where sustained write speed matters far less than capacity-per-dollar.

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.
