Standard RAID levels. In computer storage, the standard RAID levels comprise a basic set of RAID (redundant array of independent disks) configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs).
You can set up a single disk with two partitions: one to boot from and the other for data storage and have the data parition mirrored. This type of RAID is available in other operating systems as well, including OS X Server, Linux, and Windows Servers.
