Mirrored Striped Volume

RAID 0+1 volumes are mirrors of striped volumes. For example, a two-disk stripe can be mirrored to two additional disks. This RAID type provides the advantages of both speed (from striping) and fault tolerance (from mirroring). You can add more mirrors to a mirrored striped volume, and you can extend this type of volume onto additional dynamic disks within the dynamic disk group.
