Seagate documents CMR for the IronWolf Pro family; this part number is not named individually. The answer comes from Seagate IronWolf Pro NAS hard drive product page, which states it at FAMILY level - it does not name this part number. Families can ship mixed recording technologies, so this is the family's answer, not a verified answer for this exact drive.

Seagate documents CMR for the IronWolf Pro family; this part number is not named individually. That is useful evidence and it is not verification: a family can ship more than one recording method - WD Red is the standing example - so for a NAS or anything that rebuilds, prefer a drive whose own part number is documented. For a single drive holding replaceable data the distinction is largely academic.

Seagate documents CMR for the IronWolf Pro family; this part number is not named individually. So the family answer is CMR, from Seagate IronWolf Pro NAS hard drive product page; we have not found a document that names this exact part number.
The recording technology is unsourced, so we cannot clear it for arrays either way. What the spec table does say: a 300TB/year workload rating, which is NAS-or-higher class duty and a 5-year warranty. For an array, prefer a 16TB drive whose recording technology is sourced, such as the ST16000VE002 (CMR).
