3.4RAID 5
RAID 5 includes disk striping at the byte level and parity. In RAID 5, the parity information is written to several drives. RAID 5 is best suited for networks that perform many small I/O transactions simultaneously.
RAID 5 addresses the bottleneck issue for random I/O operations. Since each drive contains both data and parity, numerous writes can take place concurrently. In addition, robust caching algorithms and hardware based
