Bottom line: The Seagate Desktop Drive 8000 GB 8TB external Hard Drive, 3.5 Inch, USB 3.0, PC & Notebook, Xbox & PS4, Modellnr.: STGY8000400 is a niche pick — read recent reviews before buying in the external storage category, priced around $349.99. Compare close alternatives before committing.

Seagate Desktop Drive gives you 8TB of external storage in a 3.5-inch desktop enclosure, and it has earned a 4.5 out of 5 rating across 16,498 reviews. Connect it over USB 3.0 and a Windows computer recognizes the drive automatically, with no software to install first. Mac users reformat once and then work the same way. Backing up is drag and drop, so moving a photo library, a video project archive, or a game install folder off your internal SSD takes one action rather than a setup wizard. The 8TB capacity suits people who have outgrown a 1TB or 2TB portable drive: 4K video files, RAW photo…
