: A more space-efficient form of redundancy that calculates a checksum for data blocks. If a drive fails, the missing data can be reconstructed using the parity information stored on the remaining disks. Common RAID Levels

Different "levels" of RAID offer various trade-offs between speed, capacity, and safety: Raid.rar

The technology operates through several architectural techniques that define how data is distributed across the physical disks: : A more space-efficient form of redundancy that

: This involves duplicating data across two or more disks. It provides high fault tolerance; if one drive fails, the system can seamlessly continue operating using the mirror. if one drive fails
