Crucial X9 4TB Portable SSD

The Crucial X9 4TB Portable SSD (CT4000X9SSD902) is an external solid-state drive that delivers read speeds up to 1050MB/s over USB 3.2 USB-C. Its 4000GB capacity stores large media libraries, game files and backups in a compact, rugged enclosure.

Suits mobile creators

This drive suits users who need fast, high-capacity storage that survives travel, outdoor work and accidental drops thanks to IP55 water and dust resistance and 7.5 ft drop protection. Buyers who require an internal drive for a desktop or laptop upgrade cannot use this external form factor. Users who need hardware-based encryption certified to specific standards will not find that feature here.

USB 3.2 USB-C interface

The single specification that decides fit is the USB 3.2 USB-C connection rated for up to 1050MB/s sequential read throughput. This interface determines whether the drive can connect to your devices and whether its transfer speed meets your workflow demands for large files, media editing and game loads.

Questions about this item

Which capacity should I pick for large media libraries and game installs?

The 4000 GB model gives you a single drive that holds extensive photo, video and game collections without needing multiple devices.

What does the 1050 MB/s read speed mean when I copy 4K footage to a laptop?

It lets you move multi-gigabyte video files in seconds rather than minutes, cutting wait time on every transfer.

How does USB 3.2 limit the real-world throughput of this drive?

The 3.2 interface caps the connection at the drive's rated 1050 MB/s, so you see the full advertised speed on any compatible USB-C port.
