The Seagate BarraCuda 2TB (ST2000DM006) uses CMR recording.
Verified against: Seagate BarraCuda 3.5in data sheet DS2131 · Checked
Conventional recording writes tracks side by side without overlap, so a write never forces the drive to rewrite neighbouring data. That makes the ST2000DM006 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.
This model is discontinued. Its successor is the ST2000DM008, and it is worth checking that page before assuming the replacement carries the same recording technology. Within this family it does not always.
It is CMR. That comes from Seagate BarraCuda 3.5in data sheet DS2131, 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.
The ST2000DM008. Check that model's own page before assuming it carries the same recording technology, because within this family the successor does not always match its predecessor, that is exactly the trap this site exists to catch.
