Introduction
The SAT3520U3SR USB 3.0 to Dual Bay 3.5”SATA External RAID Enclosure turns two
3.5” SATA (SATA I, SATA II, SATA III) hard drives into an external RAID array through a
USB 3.0 connection. Large capacity drives (tested with up to 4TB per bay) can be used
to greatly enhance your computer’s storage/backup capabilities. Built-in support
for multiple RAID modes (RAID 0, 1, JBOD) enables the enclosure to t the role you
most need; whether it’s greater capacity or data redundancy. The drives can also be
congured for non-RAID operation, so both drives remain independent. Compliant
with the SuperSpeed USB 3.0 specication, which can provide up to 5 Gbps of
data bandwidth (10x more than USB 2.0), large amounts of data can be transferred
or streamed faster than before. Backward compatible with USB 2.0 however, this
enclosure can still be used on older systems. The SAT3520U3SR is backed by a StarTech.
com 2-year warranty and free lifetime technical support.

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.
1. Remove the four screws holding the rear panel in place (2x top edge, 2x bottom
edge) then slide the entire rear panel assembly out from the enclosure.
2. Place the rst 3.5”SATA hard drive into the top drive bay, then slide it toward the
rear panel until the drive interface is rmly connected to the SATA connector. Repeat
this step with the second 3.5”SATA hard drive, using the remaining bay.
3. Secure the SATA drives to the frame, using the provided screws.

4. Select the operating mode for the enclosure using the Jumper located on the inside
of the rear panel assemble (see section “RAID Mode” for details).
5. Once you have set the Mode Jumper to the desired RAID mode, connect the
external power adapter to the rear panel assembly. Turn the enclosure on.
6. Wait at least several seconds for the enclosure to fully power up then press the Reset
Button, located near the jumpers, to set the RAID mode.
7. Wait several seconds for the enclosure to initialize the RAID mode, then turn the
enclosure o, and disconnect the external power adapter.
8. Reassemble the enclosure by sliding the rear panel assembly back into the
enclosure casing.
9. Fasten the rear panel by replacing the 4 screws removed in Step 1.

RAID Mode
The enclosure can be congured to operate in one of three modes (Normal/JBOD,
RAID 0, RAID 1). Switching between the dierent modes is accomplished through the
jumper and reset button located on the inside of the enclosure.
Mode Jumper Position Description
Normal
Normal (JBOD) leaves
the hard drives as
independent disks.
The operating system
will treat them each
separately.
Dierent sized hard drives
can be used in this mode.
RAID 0
RAID 0 (Stripe) combines
both hard drives into a
single large disk array.
Data is split in half
evenly across each disk
simultaneously. Read/
write performance is
increased as a result as is
disk capacity, but failure
of any one disk will result
in permanent and total
data loss.
Identical hard drives must
be used in this mode.
RAID 1
RAID 1 (Mirror) writes the
same data to both hard
drives, creating mirror
copies. This provides
redundancy in case
one drive fails, but only
provides one drive worth
of storage space.
Identical hard drives must
be used in this mode.
Instruction Manual

Changing Modes
1. Disassemble the enclosure so you can access the internal jumper and reset button
on the drive bay cage.
2. Set the jumper to the desired mode.
3. Power on the enclosure and press the reset button.
Rebuild Mode
In RAID1 mode, if one of the drives fails the HDD LED will not light up. Replacing the
drive, will cause the enclosure to automatically enter rebuild mode when connected to
a host computer. The HDD LEDs will ash at dierent rates to indicate that the RAID1
array is being rebuilt. Depending on the size of the drives, this may take several hours
to a full day or more.
Using the Storage Device
Windows XP/Vista/7/8
If you are using brand new hard drives that do not contain any data, or after changing
between RAID Modes, then you will rst need to prepare the hard drive for use before
you can write data to them. From the main desktop, right-click on “My Computer”
(“Computer” in Vista/7/8), then select Manage. In the new Computer Management
window, select Disk Management from the left window panel.
Instruction Manual
7
Locate the Disk that says it is “Unallocated” (check hard drive capacity to conrm it’s the
correct hard drive) and then right-click in the section that says“Unallocated” and select
“New Partition”.
The New Partition Wizard will appear. Follow the instructions in the wizard to complete
setting up the drive. Once complete, the Disk should show up as “Healthy” with a drive
letter assigned (i.e. E:). This drive letter should now appear within My Computer.
If you are installing a hard drive that already has data on it, then after plugging it in, the
drive should automatically show up with a drive letter assigned within My Computer.
