Redundant Array of Independent Disks (RAID)
The RAID principle (redundant arrangement of independent hard disks) combines several hard disks into one drive (the so-called logical drive). This logical drive ensures that better data security is guaranteed, which results from redundancy. Hard disks are combined in a hard disk network so that in the event of a power failure or the failure of one of the hard disks, the others remain fully functional. Thus, in the event of a data loss on one hard disk, the same data can still be accessed, given that all hard disks contain the data of the backup. All hard disks in the RAID hard disk array should preferably have the same storage size as well as the same performance characteristics to avoid complications during RAID operation.
