When using drives from the same model and batch?
Yup. Same age, same design, same failures... and array rebuilds are super intense workloads that often force a lot of random reads and run the drive at 100% load for many hours.
I've heard just in general. The resilvering process is hard on all the remaining drives for an extended period of time.
So you're saying I should be running RAIDz2 instead of RAIDz1? You're probably right. 😂
I made that switch a few years ago for that reason.
That said, as the saying goes, RAID is not a backup, it should never be the thing that stands between you having and losing all your data. RAID is effectively just one really dependable hard drive, but it's still a single point of failure.
So you're saying I should be running JBOD with backups instead of RAIDz1? You're probably right. 🤭
As long as you're ok with it being way less dependable, and having to rebuild it from scratch more often 😉.
