Hard Drive Installation Guide
1. Remove the 4 screws shown.
2. Slide out the enclosure cover.
5
NST-225MX-S3
2.5” Dual SATA 6 Gb/s to USB 3.0 HDD/SSD RAID
3. Insert the Second (lower) HDD/SSD in to the lower bay and push all the way in for
the SATA interface on the tray to make full contact with the drive interface. The
screw hole on the drive should align with the tray screw hole.
4. Insert the HDD/SSD into the top bay and push horizontally for both the SATA
interface on the tray and drive to be fully inserted. The screw hole on the drive
should align with the tray screw hole.
5. Secure both HDD/SSD with the 4 screws on each side of the Tray.
6
NST-225MX-S3
2.5” Dual SATA 6 Gb/s to USB 3.0 HDD/SSD RAID
6. Set the RAID Mode Switch to the correct setting according to RAID SW definition
table below.
IMPORTANT: If your drive have existing data AND you like to use it as Normal mode
(Individual mode), set the switch to Normal Mode and DO NOT PRESS THE RESET
BUTTON IN THE NEXT STEP (SKIP STEP #7).
Note:
☆ When you press the RESET button, it will cause a RAID mode change.
☆ HDD formatting is required whenever RAID mode changes. If you have important data on the drive, STOP,
backup your data before you continue.
☆ Make sure the enclosure is powered on before changing RAID mode.
Mode
Operation Mode Description
Normal
Normal - Write each HDD independently
(Individual)
two separate HDDs and their capacities
Just a Bunch of Disk - It concatenates two disks to a
JBOD
single drive.
Capacity equals to the sum of two disks.
RAID 0
RAID 1
Stripe - Write data evenly across both disks
Capacity is double of the smaller HDD
Mirror - Create a mirror of data on both disks
Capacity equals to that of the smaller HDD

7. This Step will set the RAID mode. Connect the power cable to the enclosure and
the ac adapter to your power outlet. While pressing the reset button, turn ON the
power switch and continue to hold the reset button for another 10-15 seconds
while the drive spin up and set the mode change. After 15 seconds later, you can
release the reset button and the mode change is done. The Green HDD LED will
continue to flash and the Red Power LED will be ON. You can now turn off the unit
and continue with the next step.
8. Slide the cover back on to the Tray and secure using the 4 Screws.
9. You can now start using your enclosure. If you need to initialize, partition and
format the drive, please refer to Chapter on Hard Drive Formatting Guide.

RAID Mode Selection
Normal (Individual): It enables each HDD to be seen separately as single drives.
RAID 0 (Stripe): It’s a combination of two physical partitions where the data is striped
between them. It presents the best data speed but no data redundancy.
Both HDDs allots the loading evenly. In short, RAID 0 stands for faster transmission.
9
NST-225MX-S3
2.5” Dual SATA 6 Gb/s to USB 3.0 HDD/SSD RAID
RAID 1 (Mirror): It allows the device to automatically copy data to both HDDs. It stores
all data in duplication to both drives to protect against data loss out of drive failure.
If one drive fails, the Mirrored volume is still usable, but it is in a vulnerable state since
the other mirrored hard drive is inaccessible. When the offline drive resumes online, the
appliance begins the rebuild process immediately to restore data redundancy.
Host access takes precedence in rebuild process. If you continue using the Mirror volume
during the rebuild, the rebuild process will take a longer time to complete, and the host
data transfer performance will also be impacted.
JBOD (BIG or LARGE): It concatenates a series of physical HDDs as a single large
volume; HDD 1 and 2 are combined into a storage capacity that is equal to the sum of
both HDDs.

Important Note!
-
All HDDs must be re-initialize, partition and formatted on every mode change operation.
-
All new HDDs must be initialize, partition and formatted in this enclosure when used in this
enclosure for the first time, except use of old HDDs under Normal mode**.
HDD capacity beyond 2TB are support via GPT (GUID) Windows Vista/7/8.1/10, OS X, and Linux.
Windows® XP 32bit OS cannot support capacity over 2TB HDD(s) and cannot be used in this
enclosure.
