Manufacturer description

Seagate's Desktop Drive packs 8TB of external storage into a 3.5-inch enclosure built for desk-bound backup duty rather than travel. Connect it over USB 3.0 and a Windows PC recognizes it automatically — no bundled software to install, no drivers to hunt down. Back up photo libraries, 4K video projects, or a music archive by dragging folders onto the drive. Mac users reformat first, then it behaves the same way. The 8TB capacity is aimed at people who have outgrown a 1TB or 2TB portable: entire Steam libraries, years of RAW photo shoots, and full-disk system images fit without constant…

SpecPicks Verdict

SpecPicks scored Seagate Desktop Drive 8000 GB 8TB external Hard Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Seagate's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does this Seagate 8TB drive work with a Mac?

Yes, but not out of the box. The drive is preformatted for Windows, which recognizes it automatically. For macOS you reformat it first, then drag and drop as normal.

Can I use this with my PS4 or Xbox?

Yes. Seagate lists Xbox and PS4 among the supported devices for this Desktop Drive. Consoles will prompt you to format the drive for game storage on first connection.

Does it need a separate power supply?

Yes. This is a 3.5-inch desktop drive, not a bus-powered portable, so it includes an 18W power adapter. You'll need a free wall outlet near your desk.

How long is the included USB cable?

The box includes an 18-inch USB 3.0 cable. That is short for a desk setup, so plan placement close to your PC or budget for a longer USB 3.0 cable.

Do I get the full 8TB of usable space?

No. Seagate notes that available storage capacity may vary — formatting overhead and the decimal-versus-binary capacity difference mean the usable figure reads lower in your file manager.
