Stripe Set (RAID 0)

A 

stripe set

 is an array made up of two or more drives. The stripe set 

distributes, or stripes, data evenly across its respective drives in 
equal-sized sections called 

chunks

.

A stripe set distributes the data among the partitions in a way that 
optimizes access speed (high performance). A stripe set does not 
have the redundancy of a mirror set or RAID 5 set.

Figure A-4 depicts a stripe set made up of three partitions on three 
separate drives. The free space of the larger drive is not used.
