Less than $10 per terabyte, grab this massive hard drive for a record-low price at Walmart

When I made my own PC, I bought a 4TB hard drive, thinking that was more than enough space. I was quickly proven wrong. Perhaps I should have bought one of the ludicrously-huge Seagate Expansion hard drives, like the one that's currently at its lowest-ever price.

You can currently buy Seagate's 26TB hard drive for $249.99 at Walmart, which equals less than $10 per terabyte. Since releasing its Black Friday deals on November 25, I've found loads of intriguing items discounted at the retailer, but this behemoth is the one that's drawing my attention most of all.

Seagate Expansion 26TB | $269.99 $249.99 at Walmart
Save $20* - We've never seen this 26GB hard drive go this low before. Note, the 'original' price Walmart lists is likely incorrect, because the 24GB model retails for $329.99. So the saving is actually even better.

The Seagate Expansion range of hard drives range from 4TB to 28TB, with options at intervals of 2TB. However only the multiples of 4 are readily ranged by Seagate, so the 26TB model is a little bit harder to find. However it's exactly the same price as the 24TB model is at discount (and also the 12TB model, strangely).

Seagate Expansions are easy-to-use desktop expansions which grant your PC or Mac a huge amount of extra space. They're not designed for gaming per se, but would be better for storing files like videos, photos, documents and projects which you import to your computer when you need them. It connects via USB 3.0 to your computer, though you need to plug it into mains power too.

Should you buy the Seagate Expansion 26TB hard drive?

There's no beating about the bush: 26TB is more than many people will need, or will ever use on their computers. But the kind of people who could use it, might really make the most of a deal like this.

I quickly stuffed my 4TB hard drive with various video projects — apparently creating your own library of self-shot b-roll footage chomps up space — and I know more serious film-makers who need tens of terabytes of storage for each project they work on.

Likewise people who work on gaming, music or animated projects might find that 26TB is a nice amount of space to fit everything they need.

You could also buy it as a big back-up for all of your files, which sits alongside a primary hard drive so you can ensure you're covered in case anything goes wrong. Common logic is to keep all of your important files in two places at once, and the Seagate Expansion could be one such place.

Even with these things in mind, you might not need 26TB, but other sizes of hard drive from various brands are also discounted:
