I don’t know if you’re talking about the sample of cases you’ve personally witnessed, or the population of all NASes in the world. If the former, that sounds significant. If the latter, it sounds like it’s probably not something to worry about.
Comment on Can I use two different drives?
empireOfLove@lemmy.one 11 months agoIf I had a dollar for every time rebuilding a RAID array after one failed drive caused a second drive failure in the array in less than 24 hours… I’d probably buy groceries for a week.

When using drives from the same model and batch?
empireOfLove@lemmy.one 11 months ago
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.
