Seagate Exos is an enterprise datacentre drive that has become hugely popular for value-focused NAS builds. It offers the lowest price per terabyte at high capacity of any common NAS-suitable drive, in exchange for more noise and heat than a purpose-built NAS drive. The live table below ranks current UK Seagate Exos prices by price per terabyte.
Where Seagate Exos fits
Seagate Exos is an enterprise datacentre drive that has become hugely popular for value-focused NAS builds. It offers the lowest price per terabyte at high capacity of any common NAS-suitable drive, in exchange for more noise and heat than a purpose-built NAS drive. It is CMR, helium-filled at the top sizes, and built for 24/7 duty.
Workload rating and warranty
Exos carries an enterprise workload rating of 550TB of writes per year, far above the 180 to 300TB of consumer NAS drives, with a 5-year warranty and a high 2.5-million-hour MTBF. That endurance is overkill for most homes but means the drive is unbothered by heavy use.
Capacities and which NAS it suits
Exos spans mid-range sizes up to roughly 24 to 30TB, and is most compelling from 16TB upwards where its price-per-terabyte advantage is largest. At smaller sizes a quieter Red Plus or IronWolf is usually the better home choice.
Exos suits NAS in a cupboard, rack or garage where noise is not an issue, and value-focused high-capacity builds.

Frequently asked questions
Can I use Seagate Exos in a home NAS?
Yes. Exos is CMR and works in Synology, QNAP, UGREEN and other NAS units. The trade-off versus a NAS-branded drive is more noise and heat, so it suits a NAS in a cupboard, rack or garage rather than on a quiet desk. In return you get the lowest price per terabyte at high capacity.
Is Seagate Exos louder than IronWolf?
Yes, a little. Exos is a 7200rpm enterprise drive optimised for performance and density rather than acoustics, so it runs louder and warmer than a 5400rpm-class WD Red Plus or IronWolf. Away from living spaces the difference rarely matters.
Why is Exos cheaper per terabyte than NAS drives?
Exos is sold in huge datacentre volumes and competes on raw capacity, so its price per terabyte is often lower than purpose-built NAS drives, especially at 16TB and above. You are paying enterprise endurance for less, with noise as the trade-off.
Is Exos good for RAID?
Very. Exos is CMR with rotational vibration tolerance and a 550TB per year workload rating, so RAID rebuilds and heavy multi-drive use are well within its design. It is a common choice for value-focused RAID 6 and SHR-2 pools at high capacity.
