RAID Configuration
On the RAID Information screen,
press the Config button to go to the
RAID Configuration screen. In
addition to RAID disk information and
status, this screen lets you make
RAID configuration settings.
For more information on RAID, see
Appendix C: RAID Basics.
RAID Level
You can set the storage volume as either None, JBOD, RAID 0, or RAID 1.
RAID configuration is usually required only when you first set up the device. A
brief description of each RAID setting follows:
RAID Levels
Level Description
None There is no existing storage volume.
JBOD The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
RAID 0 Provides data striping but no redundancy. Improves
performance but not data safety. RAID 0 requires a minimum of
2 disks.
RAID 1 Offers disk mirroring. Provides twice the read rate of single
disks, but same write rate. RAID 1 requires a minimum of 2
disks.
WARNING
If the administrator improperly removes a hard disk that should not be removed
when RAID status is degraded, all data will be lost.
Disk Settings
Using Disk Settings, you can select stripe size, choose which disks are RAID
disks.
Disk Settings
Item Description
RAID Check the boxes of the hard drives you wish to add to the
storage volume.
Stripe Size This sets the stripe size to maximize performance of sequential
files in a storage volume. Keep the 64K setting unless you
require a special file storage layout in the storage volume. A
larger stripe size is better for large files.
Create RAID Press this button to configure a file system and create the RAID
storage volume.
Remove Click to remove the RAID volume. All user data, snapshot, and
Target USB data will be removed.
