I recently got a few (5) hard drives to turn my home server into a NAS with trueNAS scale and my idea is to have 4 usable and 1 for redundancy, my question is… How does RAID work, like what is RAID 0, RAID 5, software RAID etc, and does any of that even matter for my use case?
RAID-6 is basically the same as RAID-5 but with two extra disks instead of one, allowing for any two disks to fail and giving you n-2 capacity.
