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).
RAID 0+1: Combination of striping and mirroring
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.
