RAID 0+1:
RAID 0 drives can be mirrored suing RAID 1 techniques. Resulting in a
RAID 0+1 solution for improved performance plus resiliency.
Features and Benefits
Drives: Minimum 4, and maximum is 6 or 8, depending on the
platform.
Benefits: Optimizes for both fault tolerance and performance,
allowing for automatic redundancy. May be simultaneously used
with other RAID levels in an array, and allows for spare disks.
Drawbacks: Requires twice the available disk space for data
redundancy, the same as RAID level 1.
Fault Tolerance: Yes.
