Mode Selection & Operation Guide
☆Select HDD mode function by setting switch on PCB. Each mode must be started
from “Normal”mode. Please follow the steps as below to set HDD operation
mode.
☆Backup data before formatting hard drives.
☆The device can support two equal or unequal capacity hard drives.

RAID Mode Selection
Jumper Selection & Storage Policy Definitions
Normal MODE：It enables each hard drive to be seen separately drives. When
using a SATA host controller, JBOD should only be used if the SATA host controller
provides Port Multiplier (PM) support. If a host is not PM-aware, only a single drive
is presented (driveA). No such limitation if using a USB host connection.

JBOD MODE：It concatenates a series of physical hard drives as a single
large volume; Hard drive A and B are combined into a storage capacity that is
equal to the sum of each of the physical hard drives A and B.
Once the hard drive A and B are connected to the SATA connector 1 and 2, set
jumper switch to BIG mode and reformat the hard drive A and B together to
combine one BIG volume. Otherwise the hard drives would remain two volume

RAID 0 (Fast)：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.
Two equal hard drives：The capacity is double of the smaller hard drives.
Two unequal hard drives：The capacity is equal to the sum of both hard drives.

RAID 1 (Safe)：It allows the device automatically to copy data to both hard
drives. It stores all data in duplicate on separate drives to protect against data loss
due to drive failure. It provides the highest level of data protection for critical data
that you cannot afford to lose if a hard drive fails. The capacity is equal to the
smaller of the two hard drives.
If one drive fails, the SAFE volume is still usable, but it is in a vulnerable state
because its mirrored hard drive is inaccessible. When the offline drive comes back
online, the appliance begins a rebuild process immediately to restore data
redundancy.
Although the volume remains available during the rebuild process, the volume is
susceptible to data loss through damage to the remaining drive until redundancy is
restored at the end of the rebuild and verification process. Host access takes
precedence over the rebuild process. If you continue to use the SAFE volume
during the rebuild, the rebuild process will take a longer time to complete, and the
host data transfer performance will also be affected.
