The Seagate IronWolf Pro 22TB (ST22000NT001) uses CMR recording.
Verified against: Seagate IronWolf Pro NAS hard drive product page ยท Checked
Conventional recording writes tracks side by side without overlap, so a write never forces the drive to rewrite neighbouring data. That makes the ST22000NT001 safe for every use including RAID, ZFS, a NAS, and anything with sustained random writes. A rebuild or a resilver on this drive behaves the way the array expects, which is the whole reason the distinction matters. There is no recording-technology reason to avoid this drive for any workload.

A dash means the manufacturer does not state that field for this exact model. We leave it blank rather than filling it from a retailer listing.
It is CMR. That comes from Seagate IronWolf Pro NAS hard drive product page, which is Seagate's own documentation for this exact part number rather than a capacity-level summary or a retailer listing.
Yes. Conventional recording means a write never forces neighbouring tracks to be rewritten, so rebuilds and resilvers behave normally. There is no recording-technology objection to this drive in an array, check the workload rating and warranty for your duty cycle separately.
