RAID
RAID Modes Setting
RAID refers to redundant array of independent disks. It is a storage technology that combines multiple disk drive components
into a logical unit. Data is distributed across the drives in one of several ways called "RAID levels", depending on the level of
redundancy and performance required.
Non-RAID
The two hard drives show independent volumes, each drive can be formatted and accessed separately. If one drive fails, the
other is not affected. This mode doesn't provide any performance or redundancy benefits.
RAID 0 – Disk Stripping
The drives are shown as one single volume, but the size will be two times of the drive with smallest capacities (e.g. If there
are two drives, one is 1TB and the other is 2TB, then the available volume is only 2TB).
RAID 0 will bring faster transfer speed compare to other modes, however, if one hard drive fails then the array will crash.
RAID 1 – Disk Mirroring
The drives are shown as one single volume, but the size will depend on the drives with smallest capacities (e.g. If there are
two drives, one is 1TB and the other is 2TB, then the available volume is only 1TB).
RAID 1 will bring redundancy benefits. RAID 1 mirror one drives data to the other, so when one drive fails, you can still access
data in the other drive, or you can replace the damaged drive to rebuild RAID 1 array.
We strongly recommend replacing the faulty drive immediately to rebuild data and assure continued proper backup and data
safety.
Replace fail drive in RAID 1 Mode
1. Turn the power off and disconnect USB 3.1 Type-C cable.
2. Take out faulty drive and replace new drive.
* We strongly recommend using new hard drive (the capacity must be equal or larger than the original drive). If you are using an older
hard drive (the capacity must be equal or larger than the original drive), please backup its data if needed. The rebuild process will
automatically overwrite any pre-existing data.
3. Using USB 3.1 Type-C cable to connect your computer and turn on the power. It will rebuild data automatically.
4. When a rebuilt array is connected to your PC, LED will flash rapidly to indicate data rebuilding process. (The LED will shows on HDD1
or HDD2, depending on where the replaced HDD/SSD is located.)
5. It will take several hours to rebuild RAID 1 array, depending on your drive capacity. Both HDD1 and HDD2's LED will turn steady blue
after rebuild is completed.
JBOD Mode
Two drives show up as single volume and the total capacity is equal to the combination of two hard drives capacity. If one drive fails, then
the data of two drives will be lost.
