As the name would suggest, RAID 0+1 is striping and mirroring combined. This RAID combines the best of both RAID 0 and
RAID 1. It takes a Disk stripe using two disks, and mirrors it to another set of disks for fault tolerance. Data is stripped across
several disks, each disk has partner with exactly the same data on it. You get the benefits of fast data access as in RAID 0, with
the fault tolerance of RAID 1. This configuration provides optimal speed and reliability. You need double the number of disks as
a RAID 0, half for each side of the mirror. At least 4 hard disks are needed while performing RAID 0+1. There is other RAID
configurations in addition to those described here, but these are the types most commonly used in the industry.
