Quick answer

What is genuinely cheap here today: the Seagate Exos X14 12TB at £648.00 (£54.00/TB), at or below the lowest price we have recorded for it (£648.00 on 25 Jul 2026). 2 of 9 products in the table are at or near their own recorded low; the rest only beat Amazon's reference price or are new to our tracker.

Checked 00:21, 7 October 2026

Exos is Seagate's data-centre drive and often the cheapest way to buy large capacity per terabyte, at the cost of more noise and heat than NAS-class drives. The deal table holds new SATA units only. SAS models need a SAS controller that home NAS boxes lack, and renewed drives carry shorter warranties, so both sit in a separate note below rather than in the ranking.

Verdicts compare today's price with the lowest price we have recorded for the same listing. Amazon was is Amazon's own reference price. Prices can change after our check; the price on Amazon.co.uk at checkout applies.

Used, renewed and SAS drives

Kept out of the ranking: renewed drives carry shorter seller warranties, and SAS drives need a SAS controller that home NAS units do not have.

Is it really a deal?

For new SATA Exos drives we test today's price against the lowest we logged for each listing; renewed and SAS units are kept out of the verdicts. 2 of 6 products we have re-priced are at or within 3% of their lowest recorded price; the Seagate Exos X14 12TB is equal to our recorded low of £648.00, logged on 25 Jul 2026. 4 sit above what we have recorded, such as the Seagate Exos 26TB, now 11% above our recorded low; those are in the collapsed list at the bottom. 7 prices are from an earlier check and are listed with their check date but not judged until we re-price them. For context, the lowest price per terabyte we have logged for any NAS-rated CMR 12TB drive since 30 Jun 2026 is £32.83/TB.

Frequently asked questions

Can I use Seagate Exos in a home NAS?

Yes, the SATA versions work in any NAS that takes 3.5-inch drives. Expect more noise and vibration than IronWolf or WD Red Plus, so a cupboard is better than a desk.

Will a SAS Exos drive work in my NAS?

Not in consumer units from UGREEN, Synology's DiskStation range, QNAP's home models or TerraMaster. They need a SAS controller, and the connector will not even seat on a SATA backplane.

What warranty do renewed Exos drives get?

It depends on the seller, often between 90 days and two years, against five years for new Exos. Factor that into the price gap before choosing renewed.

Which Exos generation is best value?

Whichever capacity has the lowest price per terabyte today, which the table shows. Older X16 and X18 stock can undercut newer X20 and X24 drives.
