Do you have anything you can link to explaining the 2-drive parity? Also still want to know if I'm right in understanding the risk with adding drives. It's by no means a deal breaker (ZFS demanding same-size drives is enough to drive me off), but it would obviously change how I configure it hardware-wise. Originally I was thinking "well, if I lose my crap drive, I can always recover it", but if that puts my actually decent drives at risk then it's 100% not worth it.

I'm considering using unRAID for my home NAS, but reading about how the parity drives, I'm concerned that adding older drives that I don't quite trust would lead to a greater risk of data loss. For example if I have: - New NAS-grade parity drive - HDD - HDD I could recover by losing any 1 of the drives, however, if I want to add an older 1TB drive I have laying around that I think might be less reliable than the other drives, I risk losing data of my other more reliable drives. So I guess my question(s) about this is: - Is my understanding of how parity/recovery with unRAID correct? - Would this be any different with other options such as running ZFS? - How would adding a 2nd parity drive change this? Is it literally just storing the same parity info, or do they get different cross-sections of drives so 2 could be lost?
