Ultra-compact 2TB portable SSD

The Seagate STMX2000400 is a thumb-drive sized external solid-state drive offering 2TB of storage. It connects directly via USB-C with USB 3.2 Gen 2 and Thunderbolt 3 support for broad device compatibility. The drive is built for mobility with IP54 dust and water resistance plus three-metre drop protection. It includes Seagate Toolkit software for automated backups and file syncing.

Replaces bulky external drives

This model removes the need for a separate cable by plugging straight into a USB-C port on laptops, tablets, phones or consoles. The upgrade is worthwhile when you want faster sequential reads up to 1000 MBps in a form factor small enough to attach to a keyring. It also suits users who prefer a drive made with at least 35 percent recycled materials.

Handles large media libraries

The 2TB capacity comfortably stores high-resolution photos, videos and documents for travel or field work. Sustained performance runs out when workflows demand speeds beyond the 1000 MBps sequential ceiling or require Thunderbolt-only features not supported by the host device. Buyers needing more than 2TB of space or a drive with a built-in Type-A connector should look elsewhere.

Questions about this item

Does the STMX2000400 need a cable or dock to plug into a USB-C port?

No, it has a direct USB-C connector so you insert the drive straight into the port without any cable.

What is the correct way to insert the drive so the Thunderbolt 3 link negotiates properly?

Push the USB-C plug fully home until the rubber grip sits flush; a partial insertion falls back to USB 3.2 Gen 2 only.

Can the rubber grip be replaced if it tears after repeated keyring use?

The grip is moulded onto the enclosure and is not a user-replaceable part.
