Which is faster in real use?

The Kingston XS2000, at up to 2000 MB/s versus 1050 MB/s for the Crucial X9 Pro. The Kingston only hits that speed on a USB 3.2 Gen 2x2 port; on a plain Gen 2 port both drives run closer together.

Which is better for photographers?

The Crucial X9 Pro is aimed at photographers and works with phones and Macs, and its encryption protects client files if the drive is lost. The Kingston is faster for offloading large cards and survives dust and splashes.

Does the Kingston have encryption?

No. The Kingston XS2000 lists no data encryption. The Crucial X9 Pro offers 256-bit AES hardware encryption with password protection.

The Kingston has a water and dust resistance rating, which helps on outdoor shoots. The Crucial has no such rating, so treat it as an indoor drive. Neither lists an endurance figure here.

Is the Kingston worth stepping up to?

Yes if you routinely move large video files and have a Gen 2x2 port. If you need encryption or use Android and Mac, the Crucial covers more ground.

Crucial X9 Pro Portable SSD vs Kingston XS2000 Portable SSD

The Kingston XS2000 is the faster drive on paper, rated at 2000 MB/s read and write over USB 3.2 Gen 2x2, and it carries an IP55 rating for dust and water resistance. The Crucial X9 Pro tops out at 1050 MB/s and adds 256-bit AES hardware encryption with password protection, which the Kingston lacks. Buy the Kingston for speed and rough handling, the Crucial for encrypted, cross-device work with phones and Macs.

Choose the Crucial X9 Pro if you need password-protected hardware encryption or you move files between Windows, Mac and Android phones.
Choose the Kingston XS2000 if raw transfer speed and dust and water resistance matter more than built-in encryption.
