If you’re always running out of storage for your backups or media collection, you need a big deal on an even bigger hard drive. Luckily, there’s a huge discount on a Seagate external HDD that will knock your socks off. A whopping 28TB of hard drive storage space is available, which leaves you with a huge amount of space for documents, photos, and videos.

It’s all down to Amazon, which has dropped the price of the Seagate Expansion Desktop 28TB HDD to £419.99, ready for you to pre-order before deliveries begin in a few days’ time on 17th December. There simply aren’t many other options available with this capacity, and the options that do exist involve individual drives that often cost you hundreds of pounds more, so you’ll want to jump on this deal before it releases.

For just under £15 per TB, you’re getting a traditional 3.5" hard disk drive inside its own portable enclosure. The enclosure features its own power supply, which you’ll need to hook up to a nearby socket, while using a USB 3.0 cable to connect this drive to your PC or laptop for file transfers. You’re also getting Seagate’s Rescue Data Recovery service included, just in case your drive fails and you need to try to recover your data.

You’d usually pick up an external hard drive like this one if you weren’t too worried about extremely fast transfer rates. This isn’t an SSD, after all. It’s also a good alternative to a full-blown NAS, and isn’t as expensive.

If you’re looking for a drive you can install directly into your PC, that’s not totally out of consideration, either. Some of these enclosures use enterprise-grade Exos drives, which you can remove from the enclosure itself. Shucking, as this is called, will almost certainly void your warranty, but it can be a great way to pick up a high-capacity HDD at a much lower cost. You’ll also need to research what these drives actually contain if this is your aim, however, as it can be a bit of a minefield.

This 28TB Seagate Expansion HDD is encased in an enclosure made from a rugged black plastic, measuring 7 x 2 x 5 inches, and sits on small rubber feet on the bottom of the chassis. You’ll find the power and USB connections at the back of the drive, but as I mentioned already, you can’t power this over USB. This needs the external AC power adapter to run, so make sure to keep a spare socket nearby.

You’ll also need to be close enough to your PC or laptop. You do have an approx. 45cm USB 3.0 cable, so there is a little bit of length to play with here, although you can purchase a new data cable later. Setting this drive up should be as simple as plugging it into your PC or laptop, as long as it has power.

Should you run into any issues with the drive, especially if you think it’s failed, you can call on Seagate’s Rescue Data Recovery service, which guarantees you a single in-lab attempt by professionals to recover the data. There’s no guarantee this will work, but it’s nice to have the option to try, just in case.

This £419.99 28TB Seagate Extension Desktop HDD is a very affordable price for a drive of this capacity, especially with the option to shuck it. If you want it, you can pre-order it before dispatches begin on the 17th December. There’s no guarantee that it won’t sell out before then, however, so be sure to get your orders in quickly.
