Seagate Expansion 24TB External Hard Drive HDD - USB 3.0, with Rescue Data Recovery Services (STKP24000400)

Bottom line: The Seagate Expansion 24TB External Hard Drive HDD ($679.99 on Amazon as of 2026-10-21 12:20 UTC): 24TB in one enclosure for 4K video, RAW photo, and Steam library archives; main trade-off: needs a wall outlet; the 18W adapter rules out bus-powered laptop use.

Manufacturer description

Seagate's Expansion 24TB external hard drive answers the problem most photo, video, and game libraries eventually hit: running out of room. This is a desktop-class USB 3.0 drive, so it arrives with an 18W power adapter and an 18-inch USB 3.0 cable rather than drawing power from your laptop's port. Setup is close to nonexistent — connect the cable, plug in the adapter, and Windows or Mac recognizes the volume automatically with no software to install. After that it is drag and drop: dump a camera card, park a Steam library, or archive years of project files without opening a settings menu…

SpecPicks Verdict

SpecPicks scored Seagate Expansion 24TB External Hard Drive HDD 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 the Seagate Expansion 24TB work with a Mac?

Yes. The drive is automatically recognized by both Windows and Mac with no software install. If you want to use it as a Time Machine target, you have to reformat it first in Disk Utility.

Does this drive need its own power supply?

Yes. It is a desktop drive, not a bus-powered portable, and Seagate includes an 18W power adapter along with an 18-inch USB 3.0 cable. You will need a free outlet near your desk.

How fast are transfers on this drive?

It connects over USB 3.0, which is fast enough for backups, media archives, and drag-and-drop file moves. Seagate does not publish a rated transfer speed for this model, so check the product listing for current specifications.

What is Rescue Data Recovery Services and is it included?

It is Seagate's data recovery program, and it is included with this drive alongside the limited warranty. Coverage length and terms are set by Seagate, so review the product listing for the current details.

Is the Seagate Expansion 24TB reliable enough for backups?

The included Rescue Data Recovery Services adds a safety net. It is still a single drive with no redundancy, so keep a second copy of anything irreplaceable.
