What you need is backup. RAID is not backup and is not for most home/personal users. I learnt that the hard way. Now my NAS use simple volumes only, after all, I really don't have many things I cannot lose on it. If it's something really important, I have multiple copies on different drives, and some offline cold backup. So now if any of my NAS drive is about to fail, I can just copy out the data and replace the drive, instead of spending weeks trying to rebuild the RAID and ended with a total loss as multiple drives failed in a row. The funny thing is that, after moving to simply volumes approach, I never had a drive with even a bad sector since.

Oh I have backups myself. But parent is more or less talking about a 71TiB NAS for residential usage and being able to ignore the bit rot; in that context such a person probably wouldn't have backup.

Personnaly I have long since moved out of raid 5/6 into raid 1 or 10 with versionned backup, at some level of data raid 5/6 just isn't cutting it anymore in case anything goes slightly wrong.

Yep, I get that. I was from there. My NAS is almost 10 years old now, and there are just above 60 TiB data on it, there is nothing I cannot really lose on it. I don't really have a reason to put a 20 bays NAS at home, so simple volumes turned out to be a better option. Repairing a RAID is no fun. I guess most of the ordinary home user like me should probably go with simple volumes. The cost and effort required for a RAID just doesn't justify the benefit for most home users.
