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.

Setting the RAID Mode:

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

1. Open the rear cover and pull out the plastic frame from the

aluminum-shell.

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 rear cover.

4. Connect the product into the PC USB 3.0 port by USB3.0

cable, HDD LED should turn ON to indicate the SATA hard
drives were detected.

5. Format the drives.

6. 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, it's 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.

※ BIG Mode (JBOD or Spanning):

BIG model, in this mode, 2 hard disks will simply be bound for
one, the merger hard drive performance and literacy speed will
be same as single block of hard disk, the total capacity of the
portable hard disk equal to the sum of 2 hard drives of
capacities. Once writing data, the system specify date and start
storage from the first disk, when the storage space of the first
disk use up, the data will start be stored from the back disk in
turns. If the data in the first disk appears damaged, all of the
data in the two hard disks will be totally lost.

※ FAST Mode(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
