JBOD MODE (Single)

Non-RAID (JBOD single mode): The computer
will show up 2 independent drives. This function
is the default setting when you use only one
HDD or 2 HDD (even different models) are
installed.

RAID 0 MODE (Stripping)

Stripping is a method of concatenating multiple
HDDs into one logical unit. It is the automated
process of writing data across multiple HDDs
simultaneously. Stripping is used to increase the
performance. The data are written in “column”
effect. If one HDD fails, all data are lost.

RAID 1 (Mirroring)

Mirroring is the automated process of writing
data to multiple HDDs simultaneously. It is used
to provide data redundancy. If one HDD fails, the
other HDD will continue to store the data and
provide access to it. The failed HDD can be
replaced and the rebuilt will start automatically.
The new HDD can be inserted during working
process of the system.
