Is this one CMR or SMR?

I'm going to be sarcastic and say read the description. It's right in the title.

Is this drive compatible with the Synology DS414 NAS?

The WD Red 4TB NAS Internal Hard Drive is designed for use in NAS systems with up to 8 bays and includes NASware technology for compatibility, which suggests it should be compatible with the Synology DS414 NAS.
