RAID 6+0
RAID 6+0 supports striping across multiple volumes during expansion. RAID 6+0 provides
good performance but requires a smaller number of disks than RAID 10 because parity is
distributed across the storage disks. A relatively large part of the storage space on each disk
is sequestered and dedicated to parity.
