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.

CMR or SMR? What we can and cannot source for this part number
Part of the WD line we track.
The WD Red 10TB WD100EFAX is a 10TB SATA-6G enterprise drive at $40.00/TB - Verify recording technology before use in RAID. As a refurbished unit, run SMART diagnostics on arrival and verify power-on hours.
Recording technology: Western Digital documents CMR for the WD Red line at every capacity outside the SMR models its 2020 list names; this part number is not named individually. A family can ship more than one recording method, so treat this as the family's answer rather than a verified answer for this drive.
Against every other drive we have an in-stock price for today, this one is cheaper per tb than 45% of them (109 of 244). The cheapest we can currently buy is $14.99/TB; the middle of the market is $38.16/TB.
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
Yes. At our last check it was $399.99 ($40.00 per terabyte at its 10TB capacity), sold used under ASIN B0719498XY. Amazon sets the final price at checkout.
Amazon reports this listing (WD100EFAX) as used, and its title makes no renewed or recertified claim, so the unit's origin is whatever the seller's note says - shown beside the price.
