INSERTING/REPLACING THE HARD DRIVES IN
THE RAID SYSTEM
1. Place the RAID System with its front view facing you. Position one hand on
the front edge and one on the back edge of the top lid. Simultaneously, push
the lid in the direction away from you, front to back, using your thumbs.
A “click” sound would indicate the release of the top lid security clasp.
2. Lift the top lid up to remove and expose the top view (or HDD slots). Take out
the handles from the enclosure itself and locate the HDD screws in the
packaging box.
10
(Fasten the Handles onto the HDDs)
3. Place the HDD with the metal cover side facing up and ensure that the
interface connectors are oriented toward your left side.

8. Finally, test sliding the handle to make sure that the holes glide smoothly on
the screw guides.
Repeat the same procedures for the rest of HDDs.
The auto-limiting segmented screws are designed to prevent the HDDs
or/and the handles from damages due to over-tightening. Furthermore, this
design makes the handle slide easily without any tightness.
13
9. Hold the HDD with the metal cover side facing you and the handle attached
on the upward position.
When inserting the HDD on its reverse side, the SmartGuider System
won’t be able to align and the HDD cannot be inserted.
10. Align the handle with the guide rails and slide the HDD into the indicated slot.
Firmly push downward until a “thump” sound is heard. Repeat the same
procedures for the rest of HDDs.
In most cases, you would need to firmly push the trays to a close until a
“thump” sound is heard.
14
11. Place RAID System with its front view facing you and the top lid on. Position
one hand on the front edge and one on the back edge of the top lid.
Simultaneously, push the lid firmly downward and toward you, back to front.
A “click” sound would indicate grasp of the top lid security clasp.
12. Now, the RAID System is ready for connection to a computer!

CONNECTING THE RAID SYSTEM TO A
COMPUTER
Complete the following steps to connect the RAID System to a host computer.
The RAID System should only be connected to a host computer via one
interface. Connection of the system to a computer via two or more interfaces
simultaneously is not recommended.
eSATA
DC IN

2. Insert both ends of the USB 2.0, eSATA, FireWire 400, or Fire Wire 800
cable(s) into the corresponding port of the RAID System and the host.
It is highly recommended to select only one interface to do data
transfer.

3. Turn the power switch to the “on” position.
4. When connected, the Power LED light will become steadily green, and the
HDD LED lights will become white and blink about 15 seconds. If the
HDDs are inside the RAID System, the HDD LED lights will remain
steadily white. If there are no HDDs inside the RAID System, the HDD
LED lights will turn off after blinking.
17
5. You are now ready to begin using your RAID System!
Ready
to go!
Due to compatibility issues, if you use the eSATA interface to do the data
transfer, the Silicon Image eSATA host controller is highly recommended.
Connecting Multiple Devices
Using FireWire 400 or 800, you can connect other computer hardware or digital
devices to your RAID System. This connection is called “Daisy chain”. Items
connected to the RAID System may be such as digital video camera, another
HDD, DVD writer, and much more. However, you must use the same interface in
order for the Daisy Chain to work. The computer will not recognize different
interfaces if they are all used at the same time. In addition, if a mix of
connections is used, the resulting speed will be limited to the lowest one
available.
When an additional FireWire connector is plugged in, the connector will be
viewed as a “daisy chain” port. When an additional USB or eSATA connectors is
plugged in, the connector will be viewed as its originate port, either USB or
eSATA respectively.
18
RAID MODES
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system
that utilizes multiple hard drives to share or replicate data among the disks. The
benefit, depending on the selected RAID Mode (combinations of disks), is one or
more of increased data integrity, fault-tolerance, throughput or capacity when
compared to single drives.
Deleting the current partition prior to changing RAID modes is highly
recommended.
Using identical HDDs with the same capacity and RPM, and from the same
manufacturer are highly recommended for best capacity utilization.

Fast
RAID 0 (Striping)
RAID 0 (Striping) is a performance-oriented, non-redundant data mapping
technique. It combines multiple hard drives into a single logical unit. Instead of
seeing several different hard drives, the operating system sees only one large
drive. Striping splits data evenly across two or more disks simultaneously,
dramatically increasing performance.
Striping can be implemented in disks of differing sizes, but the storage space
added to the array by each disk is limited to the size of the smallest disk.
Although Striping is an easily implemented, simple configuration, Striping should
never be used for mission critical applications. The speed of operation is
excellent in comparison to other RAID modes.
In Striping mode, it is not possible to see the HDDs as more than one unit.
If you choose to insert all 4 HDDs, it will still be viewed as one single storage unit.
When you choose to insert only two HDDs, there is not limitation on the order of
HDD insertion or the slot number.

Disk 4
In Striping mode, if one disk in the RAID System fails, all data in installed
disks will be lost.
When operating under Striping mode, it is not recommended to do HDD Hot
Swap. Any attempt to do so may result in complete loss of all data.
20
RAID 1 (Mirroring)
RAID 1 (Mirroring) consists of at least two drives storing duplicate copies of the
same data. In this mode, the data is simultaneously written to two disks. Thus,
the storage capacity of a two-disk array is combined into a single disk and the
capacity is limited to the size of the smallest disk. The speed of operation is very
slow in comparison to other RAID modes.
During rebuild, the first HDD inserted into one of the HDD slots and is recognized
by the RAID System as the source HDD. To rebuild existing data from a source
HDD to a backup HDD (target HDD), the source HDD must first be inserted into
one of the HDD slots. After the host detects the source HDD, the target HDD
should then be inserted in the other HDD tray. The RAID System will then
recognize the target HDD, the rebuild process will begin when the HDD LED
starts blinking.
In Mirroring mode, only 2 HDDs are allowed for the function to perform
properly. There is no limitation on the order of insertion or the slot number.
However, if all 4 HDDs are inserted, the RAID System can only do Mirroring in
the HDDs positioned in HDD 1 and HDD 2. It is not possible to process two sets
of HDDs at the same time.

In Mirroring mode, if one of the disks fails, either source or backup, the data
is still available. However, if the source disk fails during the rebuild process, the
data in both disks will be lost.
It is NOT recommended to do hot swap for the source disk during the
rebuild process because the data in both disks will be lost.
21
RAID 5
RAID 5 uses block-level striping with parity data distributed across all member
disks. It is also called Parity RAID. Every time a block is written to a disk in a
RAID 5 disk array, a parity block is generated within the same stripe. A block is
composed of many consecutive sectors on a disk. A series of blocks (a block
from each of the disks in an array) is collectively called a "stripe". The parity
information inside the parity block is not the identical copy of the source data. It
is generated via parity calculation. RAID 5 mode provides decent data protection
and fault tolerance. The speed of operation is average in comparison to other
RAID modes.
The number of disks supported by RAID 5 is 3 or 4. The storage capacity
will become all disks in total but minus 1. The capacity is limited to the size of
the smallest disks.

If one of the disks fails, the data can be reconstructed through parity
calculation once the broken disk is replaced with a new one.
22
RAID 5 + HotSpare
In the RAID 5 + HotSpare mode, also called HotStand, the last disk in the system
is left empty as backup. When any of the disks in the system fails, the back up
disk will automatically be rebuilt to replace the failure disk. RAID 5+HotSpare
mode provides more than decent data protection and fault tolerance. The speed
of operation is slow in comparison to other RAID modes.
Under the RAID 5+HotSpare mode, 4 HDDs in an array are required. The
storage capacity will become 3 minus 1, totaling only 2 HDD storing capacity.
But it is limited to the smallest size of HDDs, plus 1 more HDD as the backup
disk.

If one of the disks fails, the source data can be reconstructed through parity
calculation without replacing it with a new disk. In the 4-Bay RAID System, the
"Disk 4" is located in the "HDD 1" slot position.
23
RAID 0+1
In the RAID 0+1 mode, data is organized as stripes across multiple disks. And
then, the striped disk sets are mirrored. It is usually called “a mirror of stripes”.
RAID 0+1 mode provides excellent data protection and fault tolerance. The
speed of operation is fast in comparison to other RAID modes (except in RAID 0).
Under the RAID 0+1 mode, 4 HDDs in an array are required. However, the
storage capacity is only as 2 HDDs, which the total will be based on the smallest
size of the HDDs.

failed disks are in either HDD slots 2 & 3 or 1 & 4, the data will be lost.

HDD ALLOCATION
It is highly recommended to use the numbering stickers provided in the package
to help identify the HDD allocation. Although the HDD slots can help with
organization, when the hard disks are pull out without remembering their
arrangement order, the data may be lost if the HDD allocation is not the same as
the one originally set in the RAID System.

Danger: The RAID LED will blink if RAID status is in danger. For example,
RAID 5 needs to have a minimum of 3 disks. If one of the disks is not working
properly or fails, the LED indicator will blink and remind you to take actions.
(Those actions may include replacing a healthy HDD.)
Error: The RAID Alert LED will be on in RED if RAID status is in error. When the
number of disk set is not supported by certain RAID mode, or the number of disk
inserted is not the same as HDD Switch setting, RAID cannot be created
successfully.
HDD LED x 8
There are 2 LEDs for each HDD slot. The left LED indicates “Connection” and
the right one indicates “Health/Access”.

The Connection LED is only one-color (white). When the HDD is connected, the
white LED will be on. The Connection LED also indicates HDD power status and
disk rebuild status. When the target HDD is being rebuilt, the white LED will blink.
The Health/Access LED is dual-color (red/blue). The red color is for Health
condition. The blue color is for Access condition. When the HDD is not healthy,
the red LED will be on. When the HDD is being accessed, the blue LED will flash.
When HDD is healthy and not being accessed, no LED color will be on.

The difference between a flashing LED and a blinking LED is that flashing
refers to the read/write activity and blinking refers to slow but regular pulses.
SAFE REMOVAL OF THE RAID SYSTEM
Safe removal of the Enclosure from the host controller is highly recommended,
especially when switching interfaces. In order to safely remove your Enclosure
from the host controller, you would need to eject the device on your host
controller system.
If using a Mac System, safe removal of the Enclosure from the host for all
interfaces is necessary.
If using a PC System, safe removal of the RAID System from the host
depends on the interface. Most current USB and FireWire host controllers
handle USB and FireWire devices as external devices; thus, it is highly
recommended that the Enclosure be safely removed from the host if you are
using either one of the interfaces. However, if you are using the eSATA interface,
depending on the eSATA controller, the host may handle external eSATA HDD
devices as internal HDD devices. If so, safe removal of the Enclosure from the
host is unnecessary.
31
EXTERNAL BOOTUP
External Bootup may be required if the user has two different operating systems

Q&As
General
Q: How do I choose the proper RAID mode for my RAID System based on the
tasks I need to perform?
A: Since the RS-M4QO System is a “Mass Storage” device, which means its size
capacity is sufficient for data management, the different RAID mode settings can
help you administer the enormous data storage from the HDDs combination. It is
highly recommended to choose the RAID mode based on what is the essential
factor to complete your task. The most common three factors are size capacity,
speed, and data protection. For example, if using the System to simply watch
films for enjoyment, the RAID 0 mode is perfect because it can maintain decent
speed and still have a large storage capacity. However, if the work requires you
to process large files and to have a high volume of data access such as for a
graphic designer or film editor, it’ll be more efficient to choose RAID 5 or RAID
5+HotSpare modes. Both modes provide the ability to do HDD hot-swap without
affecting the data itself, and have a higher data protection level. Lastly, if the
work requires instant and continuous backup of data such as for a writer or editor,
then RAID 0+1 would be the best choice since it can provide both high data
protection and speed with less storage capacity.
HDD Capacity
Q: All my HDDs are at least 1TB or above, will the RAID System be able to
support the gigantic storage capacity? A: Yes, the RAID System will be able to support any HDDs over 1TB size
capacity. However, most older host systems cannot support over 2TB of total
capacity, only Mac OS 10.3 and newer, and PC Windows Vista or newer. In
addition, based on the host system you have, there may be limitations on the port
connections when the storage size is over 2TB. Please see the chart below.

Discrepancy in Reported & Actual Size Capacity
Q: If I have a 750GB HDD, why does the RAID System only recognized the HDD
available space as to be less than 750GB? A: Many customers are confused by their host systems when it reports a
discrepancy between reported capacity and actual capacity. Several factors can come into
play when your host system views and reports the capacity of a hard drive.
There are actually two different numbering systems used to express units of
storage capacity:
Binary, which says that a kilobyte is equal to 1024 bytes; and
Decimal, which says that a kilobyte is equal to 1000 bytes.
Most commonly used to display storage capacity is in Decimal. The surprising
fact is that even though it seems like you will have more bytes under Binary, the
Decimal calculation system actually presents a greater storage capacity. More
description on capacity issues can be found at the Seagate website under FAQs.

HDD Allocation
Q: I've pulled out all the disks inside the RAID System and now I want to put
them back, but I don't remember the HDD allocation. Will my data be safe if I put
the HDDs back into the RAID System if they're not in the correct allocation?
A: No, it would NOT be safe for your data if the HDDs were not placed back into
the RAID System in their original arrangement order. We would highly
recommend all users to use the number stickers in the package to help identify
which HDD belongs to which HDD slot. You may stick them onto the handles or
HDDs as identification.

RAID 0
Q: If I have 4 HDDs, can I create two sets of storage units by using RAID 0 mode? A: The RS-M4QO is designed to support 4 HDDs, but it cannot create or support
two sets of storage units under the RAID 0 mode. RAID 1
Q: If I inserted 4 HDDs into the RAID System to do RAID 1, and have already set
the HD Switch to 4 HDDs, why are only HDD 1 and HDD 2 LED lights staying
white? A: The RS-M4QO can only process two HDDs under the RAID 1 (Mirroring)
mode, under HDD 1 and HDD 2 slots only if all 4 HDDs are inserted. Based on
the chipset, it is not possible to process two sets of HDDs at the same time.
RAID 5
Q: If I have inserted 4 HDDs, set the RAID Switch at RAID 5, but have the HD
Switch set at 3 HDDs. Will this work? A: Yes, you may do so, but the RAID System will automatically reset the RAID
mode to RAID 5+HotSpare. The RAID System is created to determine first on
the number of HDDs inserted into the System, then the RAID mode setting.
Occasionally, the System will still reflect a “healthy” status even though the
number of HDDs inserted is not the same as the HD Switch setting. RAID 5 + HotSpare
Q: Why is the HDD 1 LED light off when the RAID System is operating under the
RAID 5+HotSpare mode? A: Due to the chipset design, the System is created to recognize HDD slot no. 1
as the backup HDD. Therefore, when one of the HDDs fails, the backup HDD in
slot no. 1 will automatically start to rebuild to replace the failed disk. 38
RAID 0+1
Q: Normally when operating under the RAID 0+1 mode, two HDDs are allowed to
fail without losing the data. Is there any special restrictions or limitations for the
RS-M4QO? A: As long as the two failed disks are not in the special combination of HDD slots
nos. 2&3 or 1&4, the data can be rebuild once the failed disks are replace with
new ones. Rebuild
Q: Does the RAID System have to be connected to the host computer when it is
in rebuild mode? A: No, it does not have to be. The RAID System can support offline rebuild,
which means it can perform the rebuild function without being connected to a
host computer.
JBOD
Q: I have 4 HDDs. Can I use them as separate HDDs on the RAID System? A: No, the RAID System does not support the JBOD (Just a Bunch Of Disks)
function. The 4-bay RAID System is specially designed for power users who
prefer enhanced storage capability and advanced RAID features.
