8.3.2 Managing a Volume
Use the Manage Volume screen to repair, expand a volume or change the volume’s RAID type. In
the Internal Storage > Volume screen, select a volume and then click Manage in the Volume
section to open the screen as shown.
The available options vary depending on the conditions it matches. For example, the Repair RAID
option is available only when a degraded volume is selected.

the top to select or unselect all entries in this column.

Choose a RAID
type 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 8 on page 50 or Section 8.6 on page 98 for more information.
Note: Use the same capacity of hard disks for RAID 1, 5, 6, or 10 to avoid wasting space.
