2 RAID Function

What is RAID?

RAID (Redundant Array of Independent Disks) is a set of technology

standards for teaming disk drives to improve fault tolerance and performance

Why RAID?

Increased data protection. If in an unfortunate event where a drive fails,

the same data is preserved on the mirrored drive.

Intelligent array controllers can apply different types of RAID for different

hard disk drives.

Increased overall network system data capacity.
Increased I/O read/write efficiency.

Changing the RAID Mode:

The RAID mode should be set before installing the drives and then first

formatting the drives.

1. Make sure the power is off.

2. Set the RAID switch and select your preferred RAID mode. There are 2
mode switches on the inner panel of the product. 4 alternate arrays can be
created through these 2 switches. View the diagram below to see the
different configuration settings for the RAID switches:

3. Install the hard drives and turn on the power.

4. Format the drives.

5. Done

Note: Changing the RAID mode will require you to re-format the drivers. Make
sure to backup all existing data first!

※ Normal Mode (Non-Raid):

Normal mode is the default setting of HDD enclosure, and will not use any
RAID mode. In Normal mode, both of the two hard disks inside the enclosure
are in an independent operation state, and also will be identified as two
separate drives in the system explorer. Users can choose any hard drive for
storing files. If one hard drive is damaged, the other hard drives data will not be
affected.

※ JBOD Mode (Spanning):

In JBOD mode two hard drives will be merged into one. Performance and
literacy speed will be the same as a single hard drive. The total capacity of the
portable hard drive is equal to the sum of the two hard drives combined. When
writing data to the JBOD array, the system will write date to the first disk. When
the storage space of the first disk is full the data will start be stored on the
second disk. If the data in the first disk is damaged, then all data in the array
