This would be 100% excellent advice if I was using this for commercial purposes... But I'm not. It is for backup purposes and sitting on a shelf in a closet in my basement.

Not sure what advice you mean. FWIW, I am also a home user, and my main NAS also lives in my basement.
Backup is a write-heavy application, since backups are rarely read. So not well suited to SMR drives, which are optimized for archival (read-mostly) use.. I'd get Ironwolf or WD Red Plus in the future.
I've never had a disk test take two months - they generally complete within 24 hours on my system. Two months suggests a problem with one of the drives, so I recommend downloading the full log zip. The summary information on the log pages doesn't give enough detail on problems with disk drives.
