Compare Recertified Seagate Exos by Price per TB
Second-hand Exos listings only, checked against 9 Seagate datasheets covering 140 model numbers

With a recertified Exos, the model number decides what you are buying. This page checks each listing against 9 Seagate datasheets covering 140 Exos model numbers. All of them give a 2.5 million hour MTBF and a five-year limited warranty for the drive when new; a workload rating appears in only 1 of the 9 sheets, and a recording type in 4. No warranty is stated on this page for any second-hand listing. The term is set by the seller and written on the listing, so read it there before buying. A listing of 22TB or more whose model number is not stated as CMR in one of the datasheets is kept out of the table and shown below it, labelled.

Checking a recertified Exos listing
- Find the model number in the title. It starts ST and contains NM, for example ST18000NM000J.
- Read the capacity from it: the digits after ST are the size in gigabytes, so ST18000 is 18TB.
- Match it to a datasheet row above. Where the row reads "Not stated by Seagate", the sheet gives no figure and none is supplied here.
- At 22TB and above, treat a model number that no datasheet states as CMR as unconfirmed: this site shows those listings only in the labelled section under the table.
- Read the seller's warranty and return terms on the listing itself. The five years in a datasheet is Seagate's term for a new drive.
Why the generation matters more than the capacity
Two recertified 16TB Exos drives can come from different datasheets, and the newest sheet is the only one that prints a workload figure at all, 550TB a year, and only beside some of its model numbers. The older sheets do not say less about the drive's quality; they simply do not publish the number, so it cannot be compared.
The same holds for recording type. Where a sheet does not name it, this page does not either.
Where the figures come from
Seagate's Exos datasheets, read on October 12, 2026. Each figure is stored against the model number it is printed beside, never against the family.

Frequently asked questions
Do recertified Exos drives carry Seagate's five-year warranty?
This page does not state one. Five years is the term Seagate's datasheets give for a new drive; a second-hand listing's cover is whatever the seller writes on it.
Which Exos datasheets state a workload rating?
DS2046.1-2512 (550TB a year on 8 of 24 models). The other 8 sheets do not state one.
Why are some large Exos listings shown separately?
From 22TB up, a listing is ranked only if a Seagate datasheet states that its model number is CMR. Model numbers that are in no datasheet we could read, several of those ending in C among them, are labelled and kept out of the ranked table.
