Tip: Format the drive to exFAT if you need to move files between Windows and Mac machines without wiping it.

Our Take

Best for: Home users and small offices that need cheap bulk storage for backups and media.

The Seagate Expansion Desktop is the workhorse of external storage. 2TB of usable space after formatting, which is enough for a full system image, years of photos, a large movie collection, and still room to spare. 0 cable, and the drive shows up in File Explorer or Finder. No drivers, no account, no software bundle to click through. 0. That is plenty for scheduled backups and streaming video off the drive, but it will not match an external SSD for editing 4K footage directly. The drive also needs its own power outlet, so it is meant to sit on a desk, not travel in a bag. The bigger selling point at this price is the included Rescue Data Recovery Services plan, which covers one in-lab recovery attempt if the drive fails. 23. For anyone who needs a lot of cheap, reliable space rather than speed, this is a straightforward buy.

Price Analysis

At $169.99, this drive is 41% below the $288.23 list price and well under every recent average - the 30-day average is $288.23, the 90-day is $277.19, and the 180-day is $262.03. That puts the current price about $92 below the six-month norm, which is the strongest position this drive has been in over that window. If you need 8TB of desktop storage, this is the moment to buy rather than wait.

Common Questions

Does the Seagate Expansion Desktop need its own power supply?

Yes. It is a 3.5-inch desktop drive, so it ships with an 18W power adapter and runs off a wall outlet rather than drawing power from your USB port.

Can I use it with a Mac and Time Machine?

Yes, but you have to reformat it first. The drive ships in NTFS for Windows, so open Disk Utility and erase it as APFS or Mac OS Extended before Time Machine will recognize it.

How fast is the 8TB Expansion Desktop?

It uses USB 3.0 with a 3.5-inch mechanical drive inside, so large file transfers typically run around 120-160 MB/s. That is fast enough for backups and media playback, but slower than an external SSD.
