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. 

-  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.
