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

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.

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
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 1 Offers disk mirroring. Provides twice the read rate of single
disks, but same write rate. RAID 1 requires a minimum of 2
disks.
If a hard disk is removed that shound not be removed when RAID status is
degraded, all data will be lost.

larger stripe size is better for large files.
