Introduction
The SAT3540U3ER 4 Drive Bay USB 3.0/eSATA to 3.5” SATA RAID Enclosure is a highperformance external RAID storage solution, supporting up to 4 high capacity 3.5”
SATA hard drives over a USB 3.0 or eSATA connection.
The 4-bay RAID enclosure can be connected to the host/source computer through
USB or eSATA and automatically builds your SATA RAID array based on your selection
(Spanning, RAID 0, RAID 1, RAID 1+0, RAID 3, and RAID 5 supported), delivering a
simple, yet exible external storage solution. Designed for convenience, the enclosure
features front panel LED indicators that provide RAID information and simple hard
drive status and activity monitoring. The enclosure also features a built-in, 3-speed
80mm fan with automatic or manual controls that allow you to customize the speed
of the fan as necessary, ensuring suitable operating temperatures for optimized drive
performance.

Installation
WARNING! Hard drives and storage enclosures require careful handling, especially
when being transported. If you are not careful with your hard disk, lost data may
result. Always handle your hard drive and storage device with caution. Be sure that
you are properly grounded by wearing an anti-static strap when handling computer
components or discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds.
Hardware Installation
1. Attach the included Hard Drive Handles to each of the hard
drives with the supplied screws and screw driver.
*installation photos for reference only
2. Press the front door in to release the latch and open the door. The door is also
removable for easier access.
3. Inside will be a metal drive cage in front of the drive bays. Along the top of the drive
cage are two small tabs. Press them down to release the cage and remove it.

4. Remove the cardboard inserts (if rst time setup) and then insert the hard drives
into the slots. Hard drives can be removed from the enclosure by pressing down on
the handles, then pulling them out.
5. Once all of the hard drives are installed, reinstall the metal cage and front door.
Make sure the bottom of the cage stays inside of the track before closing the cover.
6. Connect the power adapter DIN connector into the side of the enclosure and power
up the enclosure.
Driver Installation
No driver installation is required for the supported operating systems, as this enclosure
is natively supported, so the drivers are already installed.

How to Use
RAID Mode
While the enclosure is powered on, press and hold the ‘Mode’ button for three (3)
seconds until one of the RAID LED’s start to ash. Pressing the ‘Mode’ button will now
switch between available RAID modes. Once set, press and hold the ‘Conrmation’
button on the back of the enclosure until the enclosure powers o. Connect the
enclosure to a computer system, then power the enclosure back on and it will now be
set for the desired RAID mode.
NOTE: Changing RAID modes will destroy any existing data on the hard drives

SPAN: Spanning concatenates multiple hard drives into a
single large disk. Provides no performance or redundancy
benets.OFF
RAID 0 (Stripe): Striping combines multiple disk into a single
large disk array. The data is split evenly across each disk
simultaneously. Read/write performance is increased as a
result, but failure of any one disk will make the entire array
unusable.
RAID 1 (Mirror): Mirroring writes the same data across
multiple disk, creating a mirror copy. This provides
redundancy in case one drive fails.
RAID 3: Uses striping to write data to multiple disks like RAID
0, but reserves one disk for parity. The single parity disk is a
bottle-neck for writing since every write requires updating
the parity data. Failure of any one disk will still allow access to
the data, until the disk is replaced.
RAID 5: Uses striping to write data to multiple disks
simultaneously and distribute parity across multiple disks.
Failure of any one disk will still allow access to the data, until
the disk is replaced.
RAID 10 (1+0): Creates a stripped set, then mirrors each
stripped disk. Combines the performance of RAID 0 with the
redundancy of RAID 1.OFF

eSATA/ USB Connectivity
The LED indicators will show which host interface is currently active on the enclosure.
To switch interfaces, shut the enclosure o and disconnect old cable and then connect
the new cable and turn the enclosure back on. Only one interface can be active at a
time, so it is recommended that only one cable be connected at a time to ensure the
proper interface is chosen.

Fan Speed Control
The cooling Smart Fan is automatically controlled by an integrated thermal sensor,
but can also be set manually. The fan is capable of running at 3 dierent speeds
depending on the temperature range of the enclosure (less than 45°C, between
45°C ~ 54°C, and greater than 55°C), or set manually to run constantly at a single speed.
