Crucial X9 Pro 1TB Portable SSD: features, specs and who it suits

The Crucial X9 Pro 1TB (model CT1000X9PROSSD9) is a portable external solid-state drive that plugs in over USB-C. It gives a laptop, desktop or compatible phone or tablet a pocket-sized extra drive for files, photos and projects. The listing's own text is thin and partly in another language, so this page sticks to the specs it clearly states.

Speed: 10Gbit/s and 1,050MB/s

The listing gives a USB 3.2 connection at 10Gbit/s, with speeds of up to 1,050MB/s. The 10Gbit/s figure is the interface's top rate, and the MB/s figure is the speed the drive is listed at in ideal conditions. Real transfers depend on your computer's port, the cable, the files and whether the drive is warm. Many files copy more slowly than one large one. To reach these speeds, the computer needs a USB-C port that supports 10Gbit/s, and older or slower ports typically still work but run at a lower speed.

An SSD, not a spinning disc

An SSD stores data on flash memory with no moving parts, so it is typically quicker, quieter and more tolerant of knocks than an external hard disk. That suits drives that travel in a bag.

What IP55 protection means

The listing gives an IP55 code. The first digit covers solids: 5 means dust-protected, which limits dust entering enough to keep it from interfering with use. The second digit covers water: 5 means protection against water jets from any direction. It doesn't mean the drive can be submerged. Keep the connector dry, and check the manual for the maker's guidance.

Security and compatibility

The listing mentions AES 256-bit security, with data protection and password features. In general, this means the drive can encrypt what's on it so that someone who finds it can't read the files without the password. Whether it's active depends on the software setup, so check how Crucial says to enable it, and keep the password safe, since lost passwords can mean lost data.

Compatible systems are listed as Windows, Linux and macOS. The package includes a USB-C cable, and the listing notes there's no Wi-Fi, so it works as a wired drive.

Size

The drive measures about 5.5 x 3.5 x 0.8 inches as listed, so it is a flat, pocket-friendly shape. The listing gives a colour of grey and also mentions multi-coloured, so confirm the finish you receive.

Who it suits

It suits people moving large files between computers, creators who edit photos or video from an external drive, anyone who wants a backup copy of their files, and travellers. If your computer only has older USB-A ports, check that the cable or an adapter will work, and expect lower speeds on slower ports.

What to check before you buy

• Port speed: confirm your computer's USB-C port supports 10Gbit/s.
• Cable and adapters: check that the included USB-C cable fits your ports.
• Capacity: 1TB suits many people, but large video libraries may need more.
• Encryption setup: read how the password and data protection features work before relying on them.
• Backups: an external drive is one copy; keep important files in a second place.
• Warranty terms: read the manufacturer's current terms.
