It's quite clear that WD never properly tested these SMR drives in actual 3-8 bay NAS workloads. Certainly not a rebuild. Based on their initial response to this scandal, it seems at some point they defined the "small NAS" Red spec as 180 TB/year read/written per year. Then they later certified the new SMR drives as meeting this 180 TB/year spec, probably by testing they were good for 500gb/day. They completely ignored the fact that larger home NAS installs don't use their 180 TB/year spec at a uniform rate, but instead tear though several TB doing a rebuild then sit near idle for most of the rest of the year.
