Overview

The Seagate Backup Plus Slim 1TB (STHN1000400) is a portable external hard drive built for users who need reliable, on-the-go storage without bulk. Its brushed metal enclosure keeps the profile slim enough to slide into a pocket or laptop bag, while USB 3.0 connectivity ensures reasonably fast file transfers for documents, photos, and videos. The drive is bus-powered, drawing all the energy it needs from the USB cable, so there is no separate power adapter to carry.

Seagate's backup software simplifies data protection with one-click and scheduled automatic backups on daily, weekly, or monthly intervals, making it straightforward to keep important files safe. The drive works out of the box with Windows and is compatible with Mac after reformatting for Time Machine use. As an added bonus, Seagate includes a one-year subscription to Mylio Create for organizing and editing photos across devices, along with a two-month Adobe Creative Cloud Photography Plan membership. Backed by a two-year limited warranty, the Backup Plus Slim is a practical and affordable storage solution for everyday needs.
