MDD18TSAS25672E: CMR or SMR?
Not stated: we hold no maker document that names MDD18TSAS25672E's recording technology. We know what the drive is - a MDD 18TB SAS-12G 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. Check the drive's label against the maker's data sheet, or choose one of the drives below whose CMR status is sourced.

No seller we track has MDD18TSAS25672E 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 MDD's data sheet or product manual for that family. A document that prints MDD18TSAS25672E 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.

When a source turns up
When we find a maker document that names MDD18TSAS25672E, this page will state the answer with that document linked and the date we read it, the same way our documented pages do. Until then, the honest answer is that we do not know.
