Seagate Expansion 2TB portable drive

The Seagate Expansion STKM2000400 is a 2TB portable hard drive in a 2.5 inch form factor. It connects via USB 3.0 and is powered from the bus so no external supply is needed. The black enclosure is compact for carrying large media libraries between locations. It works with most Windows and macOS systems after a simple plug-in.

Check your host port and Time Machine needs

Verify that the computer provides a USB 3.0 port to reach the interface transfer rate; a slower port will still work but at reduced speed. The drive is automatically recognised by Windows and macOS without driver installation. For macOS Time Machine backups the drive must be reformatted first, so plan for that step before relying on it for system backups.

Cable length and Rescue service in the box

An 18-inch (45.72cm) USB 3.0 cable is included, so the drive reaches nearby ports without an extra purchase. The package also contains a quick start guide and access to Seagate Rescue Data Recovery Services where available. Bus power frees a mains socket and keeps the setup lightweight for travel or desk use.

Questions about this item

What comes in the box with the Seagate Expansion STKM2000400 and do I need to buy anything else?

The package includes the 2TB portable hard drive, an 18-inch USB 3.0 cable and a quick start guide. No separate power supply is needed because the drive is powered from the USB cable.

Should I choose the 2TB model or is another capacity available for the STKM2000400?

The STKM2000400 is offered only in a 2TB capacity. If you need more or less space, you would have to select a different model number.

What does the USB 3.0 interface mean for real-world transfer speeds on this drive?

USB 3.0 supports up to 5 Gbit/s, but actual throughput depends on the host port, cable quality and the mechanical drive inside. You will see the fastest rates when connected to a USB 3.0 port.
