Appendix C RAID 14 (1) RAID0 This method slices data (send fro m the host) in a striping size a nd distributes the data to the physical disks of the RAID. If processing is performed concurrently for the phys ical disks of the RAID, the data transfer time is reduced to 1/(number of PD s) and data can be accessed quickly. Since RAID0 has no redundant[...]

Appendix C RAID 15 (2) RAID1 This method writes data (sent from the host) onto two disks (or into 2 disk g roups). (Mirroring) RAID1 has the same data in dual configuration.
