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.

With one hard disk installed, JBOD is the default setting. If an eSATA hard disk is connected to the N199, the RAID 1 option is enabled.

For more information on RAID, see Appendix C: RAID Basics.

RAID Level

The storage volume can either read as None, JBOD, or RAID 1. RAID 1 is only available if an eSATA hard disk is properly connected. RAID configuration is usually required only when you first set up the device. A brief description of each RAID setting follows:

RAID Levels

Description

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 1

disks, but same write rate. RAID 1 requires a minimum of 2

 

disks.

degraded, all data will be lost.

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.
