RAID 0+1:
RAID 0+1 combines mirroring and striping functions on a minimum of four hard disks. Mirroring provides full redundancy
and protects data in case of multiple drive failure (providing that data on one of each mirrored pair of drives is intact).

Characteristics:
This configuration provides optimal speed and reliability.
Requires even number of disks (minimum 4 disks).
The diagram below represents the writing of data on a RAID 0+1 array composed of four HDDS connected to the
controller. The controller creates a RAID 0 array from two RAID 1 sub-arrays.
