Overview
Seagate designs the Backup Plus desktop drive as big, cross-platform backup storage with built-in options that reach iOS and Android devices. It can automatically save photos from social networks and share files between Windows and Mac computers.
Choose it for a single large place to keep a household's photos, files and device backups. The listing mentions only a USB cable, and the quoted transfer rate looks low for the interface.
Who it's for
A desk with room for a full-size drive and a collection of photos and documents on both Windows and Mac suits the capacity. Travelers and anyone needing a pocketable drive should choose a portable model.
Pros and cons
- Very large capacity
- Windows and Mac compatible
- Mobile device backup
- Automatic social photo save
- Power adapter not listed
- Transfer rate entry looks low for USB 3.0
- Desktop size, not portable
Performance notes
The mechanical disk sets sustained speed, so the high capacity comes with the slower file copying typical of spinning drives. Backup software runs on the computer and copies files in the background. The cross-platform format lets Windows and Mac read the same files.
