Setting the RAID Mode
RAID (Redundant Array of Independent Disks) is a set of
technology standards for teaming disk drives to improve fault
tolerance and performance.
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 have 2 mode switch in the inner of the product, it can
form 4 kinds of different ways through these 2 switches, it can
realize 4 kinds of different functions as below.

3. Install the hard drives and replace the front panel, then turn on
the power.
4. Format the drives.
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 condition, both of the two hard disk
mode inside the enclosure are in independent operation state, and
also will be identified as the two separate hearts in the system,
users can choose any hard drive for storing files. If one piece of
hard disk is damaged, the other piece of hard disk data would not
be influenced.

6
BIG Mode (JBOD/Spanning)
In JBOD mode two hard disk will simply be bound for one, the
merger hard drive performance will be same as single hard disk.
The total capacity of the portable hard disk equal to the sum of two
hard drive capacity. In this mode the system starts to storage from
the first disk and switches to the second hard drive when the
storage space of the first disk is. If one of the two HDDs appears
damaged, then all of the data in the two hard disk will be lost.

7
FAST Mode (RAID 0/Striping)
FAST mode it's also our familiar RAID 0 mode. In RAID 0 state,
data storage is divided into two parts, respectively in two hard disk
storage, then the theory storage speed of hard disk is twice the one
of single block hard disk.
The actual capacity equals to twice the smaller capacity of the one
hard drive (between the two hard disk). The deficiency of RAID 0 is
that any piece of hard disk is failure, the whole RAID on data will
not be restored.

8
SAFE Mode (RAID 1/Mirroring)
Safe mode is also known as RAID 1. In this state two hard drives
are closely mirrored. The actual capacity of portable hard drive
equals to the smaller capacity one, storage speed is same.as a
single block of hard disk. The advantage of RAID 1 lies that any
piece of hard disk stored data losing, others can not lose, its
weakness is the capacity loss of hard drive is bigger.
For this reason the RAID 1 mode is the ideal storage solution for
very important material such as databases or personal data.

System Setup
Hard Drive Installation
The drives can be installed at any position, there is no specific
order required.
1. Unlock the switch at the bottom of the case and lift the front
panel upward and away from the housing to remove it.
!
2. Install the hard drives as illustrated below with the top of the
drives, where the label is located, facing each other. Push the
drives lightly into place.
3. Set your preferred RAID mode and then replace the front
panel.

10
Connect to computer
1. Connect one end (type B) of the USB cable into the type 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 Power supply to the enclosure and power up the
enclosure.
4. Let 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 drives 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.

11
Replacing Hard Drives
When one drive fails, the HDD LED will display below state:
1. If HDD1 Fails: Every 3 seconds LED flash once when power
on.
2. If HDD2 Fails: LED off.
If one drive fails and the RAID mode is set to RAID0 or JBOD, the
data will be lost and the system can not be accessed again until the
drive have been replaced.
1. Check the HDD LED state and replace the faulty drive. The
power must turn off when replacing the drive.
2. For RAID 0 and JBOD, restart the system and then format the
drives again.
3. For Non-RAID (Normal Mode), simply format the new drive.

FAQs
Can I use external USB hub?
Yes, USB hub works in the same way as the computer USB ports.
My computer doesn't have USB 3.0 port, can I use USB 3.0
host adaptor?
USB 3.0 host adapter works in the same way as the built-in USB
ports.
What file system should I choose to format my drive?
This will depend on how you want to use the drive but in general,
we recommend:
•Windows XP/VISTA/7 NTFS
•Mac OS X HFS+ (Mac OS Extended)
•To use it on both PC and Mac FAT32 (single file size is
limited to 4GB)
How many drives can fail before I loose my data?
For RAID 0 and JBOD, any drive failure will result in the data being
lost. For RAID 1, more than one drive failure at the same time will
mean the data can not be recovered anymore. For Non-RAID, only
the data on the defective drive will be lost.
