Comment on What is the most efficient method to set up a home server?

Always remember: RAID is not a backup.
Having only one backup and the server dying means you now have no backup, therefore the 3-2-1 scheme for backups is worth looking into.

I wouldnt never do raid with only 2 disks, it doesnt seeem safe tbh, 3 disks min (2 disk as backup)

Raid 5 with 3 drives survives one dying disk. Raid 1 (mirroring) with 2 disks survives one dying disk. if either setup loses two disks all the data is gone.
When you run 3 disks then the odds of two failing are higher than if you run 2 disks.
So 3 disks are not significantly safer and might even be worse.
That being said: both setups are fine for home use, because you've set up real backups anyway, right?

you can use raid 1 with 3 disks gg (or 4 or 5 or 6…)
yes

Raid 1 on two drives is perfectly reasonable.

its little money vs time you spent on it (backups are almost always missing something)
