Overview

The Seagate Backup Plus Desktop External Hard Drive delivers 2TB of storage through a USB 3.0 connection, making it a straightforward solution for backing up and archiving your digital life. The included Seagate Dashboard software allows you to set up customized backup plans, scheduling automatic file copies so your important data stays protected without manual effort. A cloud storage service component also enables easy backup and sharing of select files from the drive.

One of this drive's practical strengths is its cross-platform flexibility. It ships formatted for Mac, but installing the included HFS+ driver allows seamless use between Mac and PC systems — handy for mixed-platform households or workflows. For users who need faster or alternative connectivity, an optional adapter allows upgrading from USB 3.0 to Thunderbolt or FireWire 800. As a desktop unit, it is designed for stationary use and requires external power, but in return offers reliable, always-available storage on your desk.
