HGST 0B36404 CMR or SMR?

Hi guys, does all HGST series is CMR.

I want to buy this

Western Digital HGST Ultrastar 7K8 3.5 8TB 7200rpm 256MB SATA3 HUS728T8TALE6L4 / 0B36404

and use it with FREENAS with ZFS but i cant find info CMR or SMR?
Does HGST is better or WD RED PLUS?
Thx in advance to everyone.

nope

here’s a HGST 15TB DC HC620 which clearly states SMR.
