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.
