Rebuilding an array always sucks. No doubt. Hope you have 2+ drive redundancy and the array can still perform during the healing process.

BUT... CMR is objectively better than SMR in every way but price. Is that not the case? Wasnt there a shit show about how WD reds were lying about drives actually being shingled?

And in the world of WD Gold, Seagate EXOS... etc.... you cant even buy an SMR drive
