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

will be lost.
※RAID0 (Striping):
A RAID0 array divides data into two parts respectively in the two hard
drives. The theoretical storage speed of the array is twice that of a single drive,
and actual capacity equals twice the size of the smallest capacity hard
drive(between the two hard drives). The deficit of a RAID0 array is that if any
hard drive fails the entire RAID array will not be restored, and the data will be
lost.

※RAID1 (Mirroring):
A RAID1 array mirrors data written to the two hard drives equally. The
capacity of the array is equal to the smallest capacity drive in the array.
Storage speed is same as a single drive. The advantage of RAID1 is that if any
hard drive fails the other drive will still carry all data written to the drives. Its
deficit is that the maximum capacity of the array is equal to the smallest drive
in the array..
Note: For very important material, such as databases or personal data, this is
an absolutely safe storage solution.

3 System Setup
3.1 Hard Drive Assembly
The drives can be installed at any position, there is no specific order
required.
Step 1: Take out the four screws on the back
Step 2: Pull out the plastic frame from the aluminum-shell

Step 3: Insert the HDDs to the 7+15P SATA connectors on the PCBA. Attach
the two HDDs with the included screws
Step 4: Inset the plastic frame into the aluminum housing

Step 6: Fix the back panel by four screws
Step 7: HDD Installation completed

3.2 Connect to computer
1.Connect one end (type B) of the USB cable into the B USB Port of your
HDD enclosure.
2.Connect the other end of the USB cable (type A) into any active USB port
of the computer.
3.Connect the power supply to the enclosure and power up the enclosure
4.Let the OS search and install the driver automatically.
5.Use the disk management tool(PC) or disk utility(MAC) to create a new
partition and format the drives
6.Open “My Computer” to see your external hard drive ready to use.
NOTE:
To enjoy USB 3.0 super speed up to 5Gbps, your computer must be
equipped with built-in USB 3.0 ports, or a USB 3.0 host PCI-e card
It is not possible to add more drivers to an existing RAID array without
re-formatting it. When adding additional drivers at a later point, they will only
be detected after the device has been restarted and the drivers have been
re-formatted.
