Overview

The Seagate Backup Plus 1TB Portable External Hard Drive (STBU1000100) is designed to make data backup as simple as possible. With a USB 3.0 interface that is backward compatible with USB 2.0, it delivers solid transfer speeds for everyday file management — from documents and photos to music libraries and project archives. The drive is bus-powered, drawing all the energy it needs through the USB cable, so there is no external adapter to carry or misplace. Its compact footprint makes it easy to slip into a laptop bag for on-the-go use.

A standout feature is the included Seagate Dashboard software, which not only handles scheduled local backups but also offers the ability to save photos and videos from social media accounts — a useful layer of protection for digital content that often exists only online. The built-in NTFS driver for Mac means the drive works across both Windows and Mac platforms without the hassle of reformatting, making it a practical choice for mixed-OS environments. While the 1TB capacity and listed OS support skew toward an earlier era, the drive remains a reliable and affordable option for straightforward, portable backup needs.
