Crucial X6 Portable 4TB vs LaCie Rugged SSD Portable 2TB

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.

LaCie

LaCie Rugged SSD Portable 2TB
8.7/10

The 2TB non-Pro Rugged SSD keeps the iconic orange armor but doubles capacity. A frequent pick for outdoor photographers shooting medium-format RAW, where the IP67 rating matters more than the Pro model's Thunderbolt speeds, and the 950 MB/s USB-C is plenty fast.
