Personally I would go with RAID-6 rather than RAID-5, but with RAID-6 you are limited to the capacity of the fourth largest disk.

 

RAID-6 is used by X-RAID2 dual-redundancy as opposed to RAID-5 which is used by the default X-RAID2 single-redundancy. If you want to use X-RAID2 dual-redundancy on OS6 you can disable X-RAID, destroy the default volume, create a RAID-6 volume called "data" and re-enable X-RAID.

    At the moment dual redundancy would waste investment in 8 TB drives (giving only a 16 TB volume). Single Redundancy gives 24 TB.
