12TB drives: strong value for NAS and bulk storage

12TB consistently shows some of the better £/TB figures on the site, particularly once Renewed enterprise stock is included. The table above ranks every 12TB drive by real cost per terabyte.

  • Renewed enterprise (Seagate Exos, WD Ultrastar): tested data-centre pulls, often the cheapest £/TB at this size — check what to look for in our renewed drives guide.
  • NAS-rated: IronWolf Pro and Red Pro at 12TB are a common choice for a growing multi-bay array.
  • New desktop/external: available but usually a worse £/TB than the renewed enterprise options above.

Compare against 10TB and 14TB to find where the value curve is best on the day you buy.

Frequently asked questions

How does disks.co.uk rank 12TB drives?

We rank every 12TB drives by real cost per terabyte (£/TB) — the live Amazon.co.uk price divided by capacity — so the best value appears at the top. Prices refresh several times a day from Keepa, with 24-hour movement and all-time-low flags.

What is the cheapest 12TB drives drive right now?

The drive at the top of the table above is the cheapest 12TB drives option by £/TB at the moment. Larger capacities usually cost less per terabyte, so it is worth comparing 12TB drives against the next size up before you buy.

Is a 12TB drives drive good value?

Value depends on £/TB, not the sticker price. Use the ranking above to compare, and open any drive for its full Keepa price history to check whether today's price is genuinely low.

What is a 12TB drives drive good for?

It comes down to how much you store — see our storage sizing guide. As a rule, buy one size up if the £/TB is similar, so you do not run out sooner.
