I currently only have 2 drives installed in my NAS in a RAID 1 configuration so I cannot explore for myself, but I was wondering if it is possible to independently configure the drives for different purposes if more drives are fitted?
For example, is it possible to have 2 drives in a RAID 1 configuration and disk 3 and/or 4 for backup purposes?
I know backups ideally need to be in a different physical location but I am just curious if this is possible, or if the entire disk array can only have one option applied to it.
