It should be clear that disk striping can improve data transfer rate when the strip siz is small compared to the I/O request size. It should also be clear that RAID 0 pro vides improved performance relative to a single large disk, because multiple I/O re quests can be handled in parallel. However, in this latter case, is disk striping necessary? That is, does disk striping improve I/O request rate performance com- pared to a comparable disk array without striping?
