Part number: ST4000NT001 — decoded, with sibling variants and the warranty check.
Recertified enterprise drives are pulled from datacentre fleets, tested and resold. They are usually the cheapest route to bulk capacity, and the risk is concentrated in the first weeks - so check SMART data the day it arrives rather than the day you need it.

We do not have enough in-stock comparators of this type today to place this price against the rest of the market. The category page below ranks everything we do have.
These are third-party figures about the retail market as a whole, quoted and dated. They are not our own measurements and they do not describe this specific drive.
Resolved against manufacturer compatibility lists we read and dated, capped at 4. Vendor-listed means the manufacturer names this exact part number; fit-verified is our own check of form factor, interface and recording technology against a published requirement. Neither is a guess, and a drive the registry cannot resolve shows nothing here rather than a maybe. How compatibility actually works
