Portable 4TB storage

The Crucial X9 CT4000X9SSD9 is a 4TB external solid-state drive built for creators, gamers and anyone who moves large libraries between devices. It connects over USB 3.2 Gen 2 and delivers sequential reads up to 1050 MBps. The drive is drop proof up to 7.5 feet and rated for shock, vibration and extreme temperatures.

Included USB-C cable

A USB Type-C to C cable is supplied in the box so the drive works immediately on Windows, Mac, Android, iPad, Xbox, PlayStation and other hosts. Using the cable on a USB 3.2 Gen 2 port enables the advertised 1050 MBps read speed; on slower ports the drive will still function at the host’s maximum rate.

1050 MBps read ceiling

The single figure that decides fit is the maximum sequential read of 1050 MBps. If your workflow demands sustained throughput above that level, this drive will not meet it; if 1050 MBps satisfies your backup, editing or gaming loads, the 4TB capacity and rugged build make it a practical choice.

Questions about this item

Will the USB 3.2 Gen 2 interface or cable need replacement after heavy daily use?

The drive uses a USB 3.2 Gen 2 interface with an included USB Type-C to C cable; no user-serviceable parts are inside the sealed enclosure.

What limit appears first during sustained transfers at the rated 1050 MBps read speed?

The USB 3.2 Gen 2 interface caps theoretical throughput at 10 Gbps, so the 1050 MBps read ceiling is the first bottleneck you will hit.

How much heat or fan noise does the 4TB X9 produce when running all day?

The X9 has no moving parts or fan; its aluminium chassis passively dissipates heat and the spec lists drop proofing up to 7.5 feet and extreme temperature tolerance.
