Chapter 4 Web Configurator Basics Table 16 Create Disk Group (continued) LABEL Model Name Choose a RAID type DESCRIPTION This field shows the model of the hard disk. Select a RAID type from the drop-down list box. The corresponding space allocations of available size, data protection area, and wasted size display. Use Basic with one disk. Use JBOD with two or more disks for maximum capacity. Use RAID 0 with two or four disks for maximum speed. Use RAID 1 with two or more disks to mirror primary data to another disk(s) with high performance. Use RAID 5 with three or more disks to balance performance, hard disk capacity usage with data protection in case of disk failure. Use RAID 6 with four disks for more data protection in case of disk failure. Use RAID 10 with four disks to get better performance than RAID 6, with slightly less data protection. See Table 7 on page 36 or Section 4.4.7 on page 67 for more information. Note: Use the same capacity of hard disks for RAID 1, 5, 6, or 10 to avoid wasting space. Back Next Cancel Step 2.
