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?
[This is a good video that explains the basics and what raid setup you want for what kind of data.] (https://youtube.com/watch?v=5K8szc9gDYw)
