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 1 (Mirroring): A RAID 1 setup protects data from drive failure by simultaneously writing the same data to two hard drives. Since each drive is an exact duplicate of the other, you can continue working if one fails.
