Parity or RAID 5 adds fault tolerance to Disk Striping by including parit y 
information with the data. Parity RAID dedicates the equivalent of one disk 
for storing parity stripes. The data and parity information is arranged on the 
disk array so that the parity is written to different disk. There are at least 3 
members to a Parity RAID set. 
 

 
The JBOD is a virtual disk that can either be an entir e disk drive or a segment 
of a single disk drive.
