Cheapest storage per terabyte in 2026 UK

Hard drives and SSDs with a price-per-terabyte chart showing storage costs trending down in the UK
Looking for the cheapest storage per terabyte in the UK? We track hundreds of drives daily from Amazon UK and rank every listing by £/TB — so you can spot the best value hard drives, SSDs, and external storage in seconds.

What is price per terabyte?

Price per terabyte (£/TB) is the fairest way to compare storage deals. Instead of focusing on the sticker price alone, you divide the drive cost by its usable capacity. A £120 8TB hard drive works out to roughly £15/TB, while a £45 1TB drive costs about £45/TB — more than three times as much for the same amount of space.
That is why shoppers hunting the cheapest storage per TB almost always land on high-capacity hard drives first. SSDs and NVMe drives deliver far greater speed, but flash memory still costs more to manufacture than magnetic platters. If your goal is maximum gigabytes for minimum spend, sorting by £/TB instantly separates genuine bargains from drives that only look cheap.
TerabytePrices tracks this metric across hard drives, SSDs, NVMe drives, external hard drives, and portable SSDs — all updated from live Amazon UK listings.

Understanding value per terabyte

Why larger drives cost less per TB

Manufacturers face similar fixed costs whether they produce a 2TB or a 16TB drive. Spread those costs across more terabytes and the per-unit price falls sharply. That is why an 8TB hard drive so often undercuts smaller capacities on £/TB.
SMR drives may look cheap on paper but are a poor fit for NAS RAID arrays — see our best HDD for NAS guide for why CMR matters.

HDD vs SSD: which is cheapest?

Internal hard drives remain the value champions in 2026. The best HDD deals routinely sit well below £20/TB, while SSDs and NVMe drives cost two to four times as much per terabyte for raw capacity.
SSDs win when speed matters. Many users pair a 1–2TB SSD with a large HDD. Read our SSD vs HDD guide for current UK figures.

Tips for getting the cheapest storage

  1. Buy higher capacity drives. The price per terabyte drops significantly with larger drives. An 8TB hard drive typically costs half as much per TB as a 2TB drive.
  2. Compare £/TB, not shelf price. A £35 1TB SSD looks cheaper than a £110 8TB HDD — but the HDD delivers roughly four times the value per terabyte.
  3. Consider refurbished or renewed drives. Renewed drives from reputable sellers can save 20–40% while often including warranties. Filter by condition on our hard drives page.
  4. Match the drive type to your needs. Use HDDs for bulk storage and SSDs for your operating system and frequently accessed files.
  5. Watch for sales events. Prime Day, Black Friday, and Boxing Day often bring significant discounts on storage. Bookmark this page and check before you checkout.
  6. Check prices regularly. We update our price data daily so you can always find current best deals. For a broader market overview, read how much a terabyte costs in 2026.

Frequently asked questions

What is the cheapest storage per terabyte right now?

High-capacity internal hard drives usually offer the lowest £/TB, often beating smaller drives and most SSDs by a wide margin. Check the live table above for today's best deal.

Are larger hard drives always better value per TB?

Generally yes. Fixed costs are spread across more terabytes, so 8TB and 12TB drives typically have a lower price per terabyte than 1TB or 2TB models.

Is a cheap SSD worth it for bulk storage?

SSDs are excellent for speed but rarely match HDDs on £/TB. Use a small SSD for your operating system and a large HDD for bulk files to balance cost and performance.

Do external drives cost more per terabyte?

Yes. Enclosures and portability add cost, so external HDDs usually cost more per TB than internal drives — but they are simpler for backups and travel.

How often are these prices updated?

We refresh Amazon UK prices daily. Deals change quickly around Prime Day, Black Friday, and Boxing Day, so check back before you buy.
