Understanding value per terabyte
Why larger drives cost less per TB
HDD vs SSD: which is cheapest?
Tips for getting the cheapest storage
- 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.
- 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.
- 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.
- Match the drive type to your needs. Use HDDs for bulk storage and SSDs for your operating system and frequently accessed files.
- 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.
- 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.
