     * The RAID levels for storage allocated to your volumes.
     * RAID levels set the amount of redundancy and striping.
     * Here is a quick definition of the various RAID levels.
     * 
     * RAID 0 is a striped set of disks without parity.
     * RAID 1 is a mirror copy on two disks.
     * RAID 2 is a stripe at the bit level rather than the block level. Rarely used or supported.
     * RAID 3 is a byte level striping with a dedicated parity disk.
     * RAID 4 is block level striping with a dedicated parity disk.
     * RAID 5 is block level striping with the parity data distributed across all disks.
     * RAID 6 extends RAID 5 by adding an additional parity block;
     * thus it uses block level striping with two parity blocks.
     * RAID 10 is a stripe of mirrors, i.e. a RAID 0 combination of RAID 1 drives.
