Motherboard Manual

RAID 5:

RAID 5 stripes both data and parity information across three or more drives. It writes

data and parity blocks across all the drives in the array. Fault tolerance is maintained by

ensuring that the parity information for any given block of data is placed on a different

drive from those used to store the data itself.

Features and Benefits

 Drives: Minimum 3.

 Uses: RAID 5 is recommended for transaction processing and general

purpose service.

 Benefits: An ideal combination of good performance, good fault tolerance,

and high capacity and storage efficiency.

 Drawbacks: Individual block data transfer rate same as a single disk. Write

performance can be CPU intensive.

 Fault Tolerance: Yes.
