    The default XRAID is the simplest.  To upgrade, you'd replace two of the 4 disks with bigger ones (one disk at a time).  Then upgrade the other disks to the bigger size (or large) later on.

     

    For instance, 4x4 TB would give you as 12 TB volume (~10.9 TiB).  Upgrading two disks to 8 TB would give you a 16 TB volume; upgrading a third disk would give you 20 TB; and upgrading the last would give you 24 TB.

     

    If you follow the upgrade rule above, the capacity of the volume is easily computed - sum the disks and subtract the largest.
