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).
RAID 2 The RAID 2 configuration uses data striping (see below) and a fault tolerance technique called parity (see below), it requires at least 3 disks. Two (or more) of the disks are used to store the data and one disk is used to store the parity (see below) information. RAID 2 strips the data into bits, which is why RAID 3 (below) is a better implementation as it strips the data into bytes instead.
