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. Recording type is a per-model fact here: Seagate's data sheets list CMR for the Exos X18, X20, X22, X24 and Exos M models they cover, and from 22TB up this site ranks an Exos drive only when its exact model number is CMR in Seagate's data sheet; other listings are shown for reference, labelled.

Workload rating and warranty

Seagate's Exos data sheets give a 2.5-million-hour MTBF and a 5-year limited warranty for every model they list. They do not state a workload rate. Seagate's product manual for the Exos X24 gives a maximum rated workload of under 550TB a year for the models it covers, which are marked in the table of ratings by model number below.

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.

Where the Exos ratings come from

Each row is read from the table in Seagate's own data sheet for that model number. "Not stated by Seagate" means the data sheet's table gives no figure for that model. No retailer or reviewer figure is substituted. The Recording column says CMR only where that model's data sheet has a CMR row. Seagate sells Exos models at 28TB and above in more than one recording type, so from 22TB up this site ranks a drive only when its exact model number is CMR in a Seagate data sheet; a model that no data sheet we have read covers is shown only in the labelled reference section, whatever the listing title says.

Frequently asked questions

Can I use Seagate Exos in a home NAS?

Yes, for the models Seagate's data sheets list as CMR, which the table of ratings by model number shows. They work 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. The Exos models in the table below marked CMR have a 2.5-million-hour MTBF and a 5-year warranty in Seagate's data sheets, and the Exos X24 product manual rates the models it covers for up to 550TB a year, 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.
