1.3 Warnings and Notices
Please read the following before beginning installation.
1.3.1 General Care
• Proper grounding is strongly recommended to
prevent electrical damage to the unit or other
connected devices, including the computer host.
Avoid all dramatic movement, tapping on the unit,
and vibration.
• Avoid placing the unit close to magnetic devices,
high voltage devices, or near a heat source. This
includes any place where the product will be subject
to direct sunlight. Do NOT allow water to make
contact with the unit.
• Before starting any type of hardware installation,
please ensure that all power switches have
been turned off and all power cords have been
disconnected to prevent personal injury and damage
to the hardware.
• To avoid overheating, the unit should be operated in a
well-ventilated area.
• Remove the drives before transporting the unit to
prevent damage to the drive interfaces.
1.3.2 RAID
• Use only hard drives that are in perfect condition.
Avoid using drives that have ever developed bad
sectors during previous usage. This could lead to
possible device failure or loss of data.
• The unit supports SATA hard drives of various
specifications and different capacities. However,
we recommend using drives of the same brand and
type for optimal performance. If drives of different
capacities are used in a RAID, the capacity of the
smallest drive will determine how much of each drive
is used. The additional capacity on the larger drives
will not be used by the RAID.
• RAID level 0 will allow you to use the full combined
capacity of the drives, and offers the best data
transfer speeds. However, RAID 0 offers no protection
for the data. If one drive fails in a RAID 0, the data on
all of the drives is irretrievably lost. Before creating a
RAID, investigate the various RAID types and choose
the one that is best for your needs.
• Always back up data before switching RAID types.
Switching RAID types will destroy current data. You
must reformat your drives afterwards.
1.3.3 Encryption (RTX Secure 222-3QR Only)
• Though the Security Key port is mechanically identical
to the standard Mini-USB port, inserting Security Keys
into any other Mini-USB port may damage the keys
and render them useless. Please only use Security
Keys in RTX products.
• Likewise, inserting a Mini-USB cable or other device
into the unit’s Security Key port on the carrier may
cause internal damage and potentially lead to loss of
data.
• Any time power is cycled on the unit, the Security
Key should be installed prior to recycling the power in
order to access the data on the drive.
2 Introduction to RAID
A RAID (Redundant Array of Independent Disks) is an
array of multiple hard drives that are combined in a way
that provides faster performance and/or data safety. Your
RTX-3QR unit is capable of creating and managing several
different varieties of RAID. You may choose your preferred
RAID level based on factors such as disk capacity, desired
data safety, and desired performance.
2.1 Summary of RAID Levels
RTX-3QR supports RAID levels 0 and 1.

replicated on two separate disks.
This is a high availability solution,
but due to the 100% duplication,
only half the total disk capacity is
available for data storage. 2 1 drive
* The RAID level becomes available as a menu option when
exactly these numbers of hard drives are installed inside of
the RTX-3QR unit.
