Seagate 4TB (ST4000DMZ04): 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 Seagate 4TB 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 Seagate has published.
We hold no vendor document that defines the segments of ST4000DMZ04, so we do not decode it.
Live rankings this model belongs to: every 4TB hard drive · 4TB SATA drives · Seagate 4TB SATA. Product pages for this part number: Seagate BarraCuda 4TB ST4000DMZ04 (no current offer).
Nearest model with a sourced answer: ST4000VX013 (Seagate SkyHawk 4TB, SMR). Listed for comparison only - two part numbers can use different recording methods, so its answer is not ST4000DMZ04's.

No seller we track has ST4000DMZ04 in stock right now. That describes today's listings only - it says nothing about whether the model is discontinued.
How to settle it for this drive
Read the model number on the drive's own label, then find Seagate's data sheet or product manual for that family. A document that prints ST4000DMZ04 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.
