What it is and who it serves

The Seagate One Touch STKZ4000400 is a 4TB portable hard drive with a USB 3.0 interface and password-activated hardware encryption. It suits anyone who wants a compact, bus-powered vault for large photo libraries or project archives that travels in a bag or sits on a desk.

What to verify before ordering

Your computer must provide a USB 3.0 port to reach the stated transfer speed and supply enough bus power. The drive works with most Windows and macOS systems, though reformatting may be required for Mac. Check seagate.com/os for current operating-system details.

Build, connectors and daily use

The textured metal finish resists fingerprints and feels solid at 0.59 lb with dimensions of 0.82" x 3.15" x 4.54". An 18 inch (46 cm) USB 3.0 cable is included for flexible placement. Downloadable Toolkit software enables one-click or scheduled backups, and Rescue Data Recovery Services are available if needed.
