RAID 5 – Block-Interleaved Distributed Parity This level uses parity data for redundancy in a similar way to RAID 3 but stripes the parity data across all the disks, similar to the way in which the source data is striped. This alleviates the bottleneck on
the parity disk. A diagrammatic representation of RAID 5 is shown in Figure 19.4(f).
