Hard Drive Price per TB: Every In-Stock UK Listing, Ranked and Charted

Cheapest hard drive per TB right now

Hard drive price per TB is a listing's price divided by its capacity, shown in pounds sterling including VAT. At the top of the ranking sits Seagate Exos 26TB Internal Hard Drive (used): £20.49/TB, or £532.81 for the whole drive. The lowest total price anywhere in the field is £19.99, and that can be a far smaller drive.

The full table at the foot of this page ranks all 406 in-stock listings on Amazon.co.uk, with nothing cut off: every class, every interface, new and used, labelled in each row. A product sold in both conditions takes one row, at its cheaper offer, with that offer's condition printed. A dearer new offer may not show. It is a hard drive price per TB comparison between listings at one merchant, not a survey of shops.

Ranking caveat: a row with no capacity on record has no £/TB. It prints n/s under Capacity and a hyphen (-) under £/TB. It is sorted by its total price, so its position says nothing about value. Its price is still real, so work out the figure yourself once you have confirmed the capacity.

Hard drive price per TB chart: the UK tracker

UK tracking began on 5 November 2026, and the chart shows levels from that date. This is a tracker going forward and not an archive, and we have no earlier UK record to show you. We will not fill that gap with dollar prices converted into pounds.

Price tracking on Amazon.co.uk began on 5 November 2026. A chart needs at least two complete days, so there is nothing to plot yet.

Once two complete days are recorded, the chart plots two levels across in-stock listings, new and used together: the daily cheapest £/TB and the daily median £/TB. It stops at the last complete day, and rows with no capacity are not in it.

Those are levels, and levels move with what is listed. If a low-priced listing goes out of stock, or a batch of large drives arrives, both levels can shift while no seller has changed a price. So a change in the chart is not necessarily a price change for a given drive. For that reason this page prints no percentage change, whatever the chart seems to show. Reading it as hard drive cost per TB over time is fair only in that limited sense: what the in-stock field looked like on each day.

What price per TB hides

Price per TB is a good first filter and a poor final answer. Four things it leaves out:

• Interface. Seagate says SAS drives cannot be plugged into SATA controllers, so a low £/TB on a SAS row helps only a system with a SAS controller. SATA drives may be plugged into SAS controllers, which makes a SATA row the wider fit.
• Workload and warranty. Toshiba rates each MG Series member at 550 TB/year and gives the series a 5-year limited warranty. Two drives at one £/TB may carry very different terms, and the figure shows none of them.
• Failure rate. In Backblaze's Q2 2026 data, two 12TB models, HUH721212ALE604 and HUH721212ALE600, logged 3.34% and 1.08%. Same capacity, same quarter.
• Capacity and outlay. Seagate's Exos range reaches 32TB per drive, and Backblaze says drives of 20TB and above are now more than a quarter of its dataset. A low £/TB on a very large drive still means a large single payment, which the price column shows.

Recording technology is not printed in this table. Where a title claims CMR, treat it as the seller's claim. If you already know the size, the 20TB, 22TB and 24TB pages give a narrower field.

Using the hard drive price per TB comparison

Work down the table in this order. First rule out any row your system cannot take, starting with the interface column. Then decide whether you will accept a used drive, since new and used rows sit side by side here. Next look at the total price, because a good £/TB is no use if the single payment is more than you planned. Last, take the part number from the row to the maker's own document, and rely on that for any specification.

Does the cheapest per TB change your UK rights?

No, though the price matters to how they are judged. Under the Consumer Rights Act 2015, goods bought from a trader must be of satisfactory quality, and the price can be relevant to that test. The short-term right to reject runs to the end of 30 days, for a used drive at the top of this ranking as much as for a new one, when the seller is a trader. These rights belong to a consumer: an individual acting for purposes wholly or mainly outside their trade, business, craft or profession.

Those statutory rights are not a manufacturer's warranty. A warranty length belongs to a maker document for a specific line, so the ranking prints none. For a narrower question, cheap enterprise hard drives separates new from used, and best enterprise hard drives states a ranking rule for one class.
