872745001: CMR or SMR?

Not stated: we hold no maker document that names 872745001's recording technology. We know what the drive is - a HP 4TB 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 872745001 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 HP's data sheet or product manual for that family. A document that prints 872745001 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.

Documented HP drives at 4TB

We hold no maker document for any HP drive at 4TB yet, so there is no documented sibling to compare against.

When a source turns up

When we find a maker document that names 872745001, 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.
