16-1. Supplement Volume Construction & RAID Configuration 3. RAID0 striping volume The Disks are configured in parallel so that they are all being used at once to store data, as if they were one Disk in summation. Because the data is saved to each Disk in parallel, many files of low capacity are read simultaneously but with superior efficiency. Many low capacity files are read because multiple blocks of data are stored to each Disk, though the performance is excellent at this time. In order to secure data stored, Information is not read when at least one Disk is damaged. Subsequently, if the Disk is damaged, the saved data in the volume will be lost. The storage capacity of the volume as a whole is the sum of the capacities of all of the Disks. This technique must not be used for the saving of important data, but rather for fast data access and for maintenance of the security of its volume capacity. 4. JBOD Linear volume The Disks are configured in series so that they are all being used at once to store data, as if they were one Disk in summation. The volume's storage capacity can be maximized, as the data is stored to the Disks in sequence. Data must not be written in the event of a damaged Disk to safeguard saving capacity. In this way, if a Disk is damaged, saved date in the volume will be lost. The storage capacity of the volume as a whole is the sum of the capacities of all of the Disks. To maximize the safeguard of capacity of the volume, saving of important data is not recommended. 107
