+	  If both <guilabel>Redundancy (mirror)</guilabel> and <guilabel>Optimized performance (stripe)</guilabel> are checked but only two disks are included in the RAID device (refer to step 4), the device level will be RAID 0+1 rather than RAID 10. RAID 0+1 creates and stripes between two partitions on the first disk and mirrors the first disk to the second. A genuine RAID 10 device will only be created if four disks are included.
