Seagate Expansion 20TB External Hard Drive - Desktop Backup

In this review the Seagate Expansion 20TB external hard drive is presented as a straightforward desktop storage solution for users who need a lot of space without fuss. The bottom line: this drive is best for home, office, and console users who want plug-and-play capacity and a simple setup, with the added reassurance of included Rescue Data Recovery Services. It does not aim to be a portable performance leader, but it delivers large, reliable desktop storage and easy file transfers for anyone who values capacity and hassle-free operation.

Key Features

• Plug-and-play setup: Connect the included 18in USB 3.0 cable and 18W power adapter and the drive is ready for drag-and-drop file saving on Windows and Mac without extra software.
• Fast file transfers: USB 3.0 support allows faster transfers than USB 2.0 so moving large photo, video and game files is more efficient.
• Large desktop capacity: The 20TB size provides enormous room for photos, movies, music, backups and console libraries so users can consolidate many files on one drive.
• Automatic computer recognition: The drive is recognized by Windows and Mac for simple setup, and can be reformatted for Apple Time Machine backups if needed.
• Rescue Data Recovery Services: Included recovery service adds peace of mind in case of accidental data loss or drive issues.

Who It's For

The Expansion 20TB is ideal for photographers, video hobbyists, families, and gamers who need bulk desktop storage that is simple to use; it is especially useful for PS4 and Xbox owners who want extra game library capacity. Small offices and dorm users who want a central desktop archive without complex configuration will also appreciate the straightforward setup and big capacity.

Users who need a compact portable drive, the absolute fastest NVMe-like transfer speeds, or a drive preformatted specifically for Time Machine without reformatting should look elsewhere. Those wanting enterprise-class redundancy or multi-drive RAID arrays will need a different product.
