O.K. you have 6x1TB with 4TB usable. Add 3x2TB disks giving you an additional 3TB usable (horizontal expansion). Add a further 2TB disk this gives you an additional 1TB horizontal expansion. Then on top of this there is vertical expansion, with a new RAID-6 layer of 4x1TB giving 2TB of vertical expansion. Remember expansion can only take place when redundant space can be added.
