Crucial X10 4TB Portable SSD

The Crucial X10 is a 4TB external solid-state drive that connects through USB 3.2 Gen 2x2 and delivers sequential reads up to 2100 MBps. It is built for creatives, gamers and professionals who need high-capacity portable storage that can be plugged into a wide range of devices without extra software.

Broad device support with rugged IP65 rating

Windows, Mac, Linux, Android, iPad, Xbox and PlayStation are all supported through a plug-and-play USB-C cable. The drive carries an IP65 dust and water resistance rating and survives drops from 9.8 feet, making it suitable for field work and travel. Buyers who need internal drive installation or a different physical connector should consider other form factors.

USB 3.2 Gen 2x2 interface determines host speed

The USB 3.2 Gen 2x2 connection is the single specification that governs maximum transfer performance. If the host port only supports an older USB generation the drive will still function but will not reach the advertised 2100 MBps read speed, so verifying the host capability is essential before purchase.

Questions about this item

What cables or accessories come with the Crucial X10 4TB CT4000X10SSD9, and is a power adapter required?

The drive connects via a plug-and-play USB-C cable and draws power from the host port, so no separate power adapter is needed.

Should I choose the 4TB X10 over a smaller capacity if I need maximum sequential read speed?

All X10 capacities share the same USB 3.2 Gen 2x2 interface and are rated up to 2100 MBps sequential read, so the 4TB model delivers the same headline speed as smaller versions.

What does the 2100 MBps sequential read figure mean when I plug the CT4000X10SSD9 into my laptop?

It is the maximum throughput over USB 3.2 Gen 2x2 for large, sequential files; actual speed depends on your port generation, cable quality, file size and system overhead.
