untick Use current disk configuration and customize these settings, then click
Apply.
NOTES:
File system type
We recommend that you use the ext2 file system.
Volume types
Standard (Single Disk): You can only install one hard disk. If it is damaged, all data is lost.
Maximum Volume - JBOD: JBOD requires two hard disks and is ideal for storing a large
amount of data. The total capacity of a JBOD volume is the sum of two disks.
Best Performance - RAID 0 (Striping): RAID 0 requires two hard disks and is ideal for fast
data access. It offers a data stripping process that divides data into blocks and spreads the
data blocks across two disks.
Maximum Security - RAID 1 (Mirroring): RAID 1 requires two hard disks and is ideal for
backing up important data. The content of one disk is duplicated to the other disk to ensure
data security, but the actual available storage capacity equals to the capacity of one disk.
Comparison of volume types
Volume type Number of hard disks Data protection Data access speed
Standard 1 None Good
JBOD  None Good
RAID 0  None Great
RAID 1  Strong Good
IMPORTANT:
Before changing the file system and volume types, back up your data on the hard disks.
