The latest addition to Crucial's range of external SSDs is the X9 Pro. A pocket-sized drive, the X9 Pro comes in three capacities and uses a USB 3.2 Gen 2 x1 (10Gb/s) interface. With the 2TB version currently retailing for £110 here in the UK, is it worth buying?

At launch, the X9 Pro comes in three capacities, 1TB, 2TB (the drive we are reviewing here) and a flagship 4TB model. The drive uses a Silicon Motion SM2320 controller which has a built-in USB 3.2 Gen2 x 2 (20Gb/s) interface but for the X9 Crucial is using it at  USB 3.2 Gen 2 x1 (10Gb/s) speed. The drive uses Micron's B47R 176-Layer 3D TLC NAND.

Officially the drives are rated as up to 1,050MB/s for Sequential reads and writes.

The drive also supports password protection and 256‐bit AES hardware encryption and carries an IP55 rating for water/dust. It can survive a drop of up to 2 meters (on a carpeted floor) although it would be a little worrying if it couldn't. Crucial backs the drive with a 5-year warranty.
