Choosing a 10TB NAS drive
Today the best value is HGST Ultrastar He10 at £278.33 (£27.83/TB). 10TB is the middle of the NAS range: enough for a media library in a two-bay mirror, or a large shared archive in a four- or five-bay RAID 5. The NAS lines (IronWolf, Red Plus/Pro, N300) and the enterprise drives (Exos, Toshiba MG, Ultrastar) overlap here, so compare the family table below on £/TB before settling on a brand.
- 2-bay, RAID 1 (mirror): 10TB usable from 2 × 10TB, about £556.66 in drives at today’s best price.
- 4-bay, RAID 5: 30TB usable from 4 × 10TB, about £1,113.32 in drives at today’s best price.
- 5-bay, RAID 5: 40TB usable from 5 × 10TB, about £1,391.65 in drives at today’s best price.
- 8-bay, RAID 6: 60TB usable from 8 × 10TB, about £2,226.64 in drives at today’s best price.

Frequently asked questions
How does disks.co.uk rank 10TB NAS drives?
We rank every 10TB NAS 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 10TB NAS drives right now?
The drive at the top of the table above is the cheapest of the 10TB NAS drives by £/TB today. At larger sizes the enterprise Exos, Toshiba MG and Ultrastar drives are often cheaper per terabyte than the NAS-branded lines; they are louder, but carry 5-year warranties.
Are all of these drives CMR?
The NAS-rated families listed here — IronWolf and IronWolf Pro, WD Red Plus and Red Pro, Toshiba N300 — and the enterprise drives all use conventional (CMR) recording. The one to watch is plain "WD Red" (no Plus or Pro) in the 2–6TB sizes, which is shingled (SMR) and a poor fit for RAID. See SMR vs CMR.
How many 10TB NAS drives do I need?
It depends on the bay count and RAID level: two drives in RAID 1 give you one drive's space with a full mirror; four in RAID 5 give three drives' worth and survive one failure. The section below works out usable space and cost at this size, and our NAS drive guide covers the choice in more detail.
