I'm actually in this boat right now. I have 2x26TB drives in a 4 base nas (two empty, plus 3x M2 empty) and I'm trying to decide the best way to set them up. I have around 3TB of backups that I care about as backups (but they don't need to be online, just archive backups at this point), and around 5TB of media that can be replaced.

I don't want to lose 26TB just for a mirror, and I have a spare 8TB USB HDD. I'm torn between unraid and just Debian, and I'm torn between just two separate devices and one RAID 1 partition one RAID 0
