RAID is basically a group of disks, usually with one or both characteristics of parity and striping. Parity is redundancy of your blocks of data on the disks; striping allows the individual drive speeds and feeds to add up, giving you more performance than a single disk could provide.
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).
