Extending the warranties on SMR drives does _nothing_ to solve the performance issues. The drives were marketed for use in NAS RAID systems, but the abysmal performance (due to the drives' SMR) in many cases will cause the NAS or RAID system to kick out the drive as a bad drive.

Given that RAID rebuild times are increasing as the size of the drives are increasing, and SMR exacerbates the longer rebuild times, these drives should not be used in the NAS or RAID systems for which that they were marketed.

By obfuscating the use of SMR in their WD Red line, WD willfully and intentionally harmed their customers.
