You might want to read the section in the manual on managing disks.

Normal XRAID behavior as you add disks:

1 6 TB disk -> 6 TB capacity, JBOD

2 6 TB disks -> 6 TB capacity, RAID-1 (single redundancy)

3 6 TB disks -> 12 TB capacity RAID-5 (single redundancy).

4 6 TB disks -> 18 TB capacity RAID-5 (single redundancy).

There are some other options, if you switch to flexraid.  However, you can't undo what's already been done unless you start over (either switch to flexraid, destroy the volume and recreate it, or do a factory reset).  Either way you lose any data on the NAS.

If you start again, I'd strongly recommend JBOD (2 6 TB volumes) instead of RAID-0 (1 12 TB volume).  RAID-0 is more fragile - if either disk fails you'd lose everything. With JBOD, a disk failure only loses the files on the disk.

While we're on the subject of data loss - you should invest in a backup strategy for the NAS.  RAID is nice, but not enough.
