In the previous table, each "Data Segment n" represents a group of data, known as a strip. In this case,

each row represents a stripe. RAID 0 represented in the table above shows how information is segmented,

made into chunks or strips, and stored across the stripes of the hard drive members of this RAID volume.

To better illustrate the concept of RAID 0 and striping, the following graphic shows how a sequence of

data "ABCD..." is stored in a RAID 0 mode. In this example, each letter represents a segment or strip. The

graphic shows how the various pieces of the information go to different hard drives. If any segment of

RAID 0 fails, all information from all members is lost.
