I wanted to revisit this after checking my own anecdata. (But based on logfiles not just like recollections.)
I've had a ZFS system or some sort for about 10 years, and before that I had proprietary RAID chassis like Pegasus2 and Synology etc.
I can't quite say how many drives I have used, because my records are not that good. But maybe its like 100 drives since 2008. Maybe 150. Less than 200.
I had over 10 HDD devices fail (probably 13, confidence of like 90%).
I've only ever had 1 SSD fail.
I've also used the absolute cheapest shite SSDs.
I suspect the failure modes tend to be
- hard disks fail whenever the fuck, who knows
- SSDs fail in the beginning or end of their reasonable service life
P.S.
With ZFS though, you don't really care if/when they fail. I've so far (knock on wood) never lost any data with a ZFS config with >1 disk redundancy and reasonable backups.
