2.3 RAID LEVELS
2.3.1 DISK STRIPING (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is
discussed as a RAID Group type, it is does not provide any fault tolerance. With modern
SATA and ATA bus mastering technology, multiple I/O operations can be performed in
parallel, enhancing data throughput. Striping arrays use multiple disks to form a larger virtual
disk. The figure below illustrates a three-disk stripe set. Stripe one is written to disk one,
stripe two to disk two, and so forth. RAID 0 sets can be comprised of two, three, or four
drives. If the sizes of the disk segments are different, the smallest disk segment will limit the
overall size of the RAID Group.
