Manufacturer description

The Seagate Backup Plus Portable 4TB gives you a full 4TB of USB 3.0 storage in a slim, minimalist metal enclosure built to travel alongside a laptop rather than sit on a desk. Setup is deliberately plain: plug the drive into a PC or Mac with the bundled USB 3.0 cable, then back up files with a single click or schedule automatic daily, weekly, or monthly backups so your photo library and project folders stay current without you thinking about it. Mac owners should note that reformatting may be required before the drive works with Time Machine, since it ships ready for Windows out of the box…
