Key Specs

Plug-and-Play Storage for PC & Mac

The Seagate Expansion STKM5000400 is ready to use straight from the box. There’s no software to install—just connect the included USB cable to a USB 3.0 port and your system will recognise it instantly. It works seamlessly with both Windows and macOS, making it a versatile storage upgrade for mixed-device households or offices.

USB-Powered Convenience

Because this drive draws power directly from the USB connection, there’s no need for a separate power adapter. That means fewer cables to carry and no extra power sockets required—perfect for travel, fieldwork, or tight desk setups. The single-cable design also speeds up setup and reduces clutter.
