Part number: ST20000NM003D — decoded, with sibling variants and the warranty check.
SAS drives do not plug into a normal SATA motherboard port. You need a SAS host bus adapter or a backplane that speaks SAS - an LSI/Broadcom HBA in IT mode is the usual answer. A SATA drive will run on a SAS controller, but not the other way round. HBA and IT-mode guide
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.

The listing's own title says "renewed" for the ST20000NM003D. That is the seller's claim; we store it verbatim and the warranty is the reseller's, not the manufacturer's. The stored warranty on this row is 5 years, as the listing states it.
