The WD Purple Pro 26TB (WD260PURP) uses CMR recording.
Verified against: WD Purple Pro smart video hard drive product brief 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 WD260PURP 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.

It is CMR, per WD Purple Pro smart video hard drive product brief - WD's documentation for this exact part number - which also rates it at 550TB/year workload.
Yes: WD Purple Pro smart video hard drive product brief states CMR for the WD260PURP, and conventional recording means a write never forces neighbouring tracks to be rewritten, so rebuilds and resilvers behave normally. Check the workload rating and warranty for your duty cycle separately.
