WD 14TB (WUH721414ALE6L1): Recording Status
We have not found a manufacturer document stating the recording technology for this exact part number. We know what the drive is - a WD 14TB SATA-6G hard drive (3.5") that we track - but a recording technology printed without a source is a guess, and for RAID, NAS or ZFS use that guess is the one that matters. That is a statement about what we have found, not about what WD has published.

How to settle it for this drive
Read the model number on the drive's own label, then find WD's data sheet or product manual for that family. A document that prints WUH721414ALE6L1 in its own row of a recording-technology table settles the question. A family page that names no part numbers does not: we have found maker pages that list neither a part number nor a recording method, and we no longer count them as sources. A retailer listing is not a source either - it is a seller's description, and sellers repeat what other listings say.
