    Which brand and model disks and what capacity have you installed?

    X-RAID2 volumes have the capacity of all the disks - the largest for redundancy.

      You do need to know the specific details of the disk sizes to compute capacity.  Your result is about right for 2x4TB+1TB, but is too low for 3x3TB.

       

      The rule for single redundancy is to sum the disks, and then subtract off the largest.  After that you need to convert TB to TiB (since the NAS reports TiB).  You do that by multiplying by .9 (value is approximate but close enough for most purposes).

       

      Let us know the sizes of your disks, and we can verify.  Model numbers might also be useful (since not all disks are compatible).
