What is RAID5?
RAID Level 5 distributes the parity among the drives. This can speed small writes in multiprocessing systems, since the parity disk does not become a bottleneck. Because parity data must be skipped on each drive during reads, however, the performance for reads tends to be considerably lower. RAID Level 5 is n-1 meaning you lose the disk space of one drive in order to stripe data across the drives. A minimum of three drives is required for RAID5.
