Well I wasn’t trying to, exactly. Just trying to convey that RAID5 is not considered reliable and that I was urging the commenter to ensure they have a backup if that’s what they are going to use. Regardless of how you configure your NAS, you can always lose data by mistake.

Please consider RAID6 or ensure your data is fully backed up. RAID5 falls flat if a drive fails during resilvering the array.
