of some of the more exotic RAID levels you may come across.
||Like RAID 5 (block level striping and distributed parity), but with dual parity for each data block
||Improved fault tolerance over RAID 5 - can handle the failure of any two drives in the array
||Slower writes than RAID 5
||Striping (RAID 0) across RAID 3 (byte-level striping with dedicated parity disk) sub-arrays
||RAID 0-like speeds, with increased fault tolerance
||Complex, expensive to implement
||Mirroring combined with block striping and distributed parity
||Maximum fault tolerance and availability through mirroring and distributed parity
||Low storage efficiency
