About RAID Mode
JBOD (NON RAID)
The two physical disks are read as two independent hard drives in a single housing.
Therefore, the computer will show two separate drives.
Note: While in JBOD mode with two drives, make sure that your system supports
Port-Multiplier in order to detect both drives. If not, only the top drive will be detected.
BIG (CONCATENATION)
The two physical drives are combined so that one single yet larger logical
volume mounts on the desktop, offering maximum possible capacity (the
available capacities of each disk are combined).
Note: If one physical disk fails, the data on both disks will become inaccessible. If you are
concerned about data security, we highly recommend using Safe configuration (RAID 1 mode).
RAID 0 (FAST)
The two physical drives are stripped together so that one larger logical volume
mounts on the desktop. Storage capacity equals twice the capacity of the smaller
hard drive (the available capacities of each disk are combined) yet with greater
speed than the Big mode (the speed of each disk runs faster to a certain level).
Note:If one physical disk fails,the data on both disks will become inaccessible.If you are
concerned about data security, we highly recommend using Safe configuration (RAID 1 mode).
English English
The two physical drives are "mirrored" so that one single logical volume mounts
on the desktop. All of the data on one drive will be recoverable from the other
drive (the available capacity of one drive cannot exceed the available capacity of
the other drive).
Note: In case both drives fail at the same time, it is recommended to backup any stored
data onto another HDD periodically for extra security.
1. While setting up RAID 1, If one of the hard drives malfunctions, check the error indicator
light in the front to see which drive has failed. Simply remove the malfunctioning hard
drive from the enclosure, then insert a new identical hard drive while the enclosure is
powered on. Close the front panel along with the new drive and the error indicator light
will disappear in a few seconds. After replacing a new drive, the rebuilding process will
start promptly. The new drive will become the new target drive while the remaining
working hard drive will become the source drive. It is recommended to use new hard
drives to replace the malfunctioning hard drive if you are using RAID. If you replace
hard drives that has been used for RAID before, the system may not function properly
due to existing RAID table on the hard drives.
2. It is normal that the enclosure will perform the data rebuilding verification after swapping
one of the hard drives when using RAID 1. The rebuilding verification process time may
vary depending on the hard drive's specifications. It usually takes about ten minutes to
verify/rebuild a 100GB capacity.
3. Do not replace both drives in any RAID mode, as both drives will cause the enclosure
to rewrite the RAID table. Once this done, the drives will no longer function in original
RAID array.
4. RAID 1 is not suggested for hard drive duplication, please do not switch the drive order
in any RAID mode. It is recommended to use the identical hard drive to ensure stability
and performance. Removing or changing any hard drive in RAID 1 while in operation
may result in data loss.
