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

Crucial

Crucial X6 Portable 4TB
8.0/10

A 4TB portable at the X6's budget price is closer to spinning-rust economics than SSD. The 800 MB/s ceiling doesn't matter for the use case — the entire point is capacious portable cold library overflow for PS5, Xbox, or photo archive, not peak throughput.

WD My Passport SSD Portable 2TB
8.7/10

A 2TB WD My Passport SSD in the same slim form factor. Both USB-C and USB-A cables in box, hardware encryption in WD Dashboard software. A value pick vs the T7 2TB when on sale — with the caveat that the 3-year warranty is shorter than Samsung's.
