1.3 RAID Mode Explanation
● Any change of RAID mode will cause data rebuild and data lost.
①RAID MODE 6
②RAID MODE 0
③RAID MODE 3
④RAID MODE 5
Data
Drive
Parity Data
Drive
Data and
parity are
equally
distribute
d among
6 drives
The most bottom drive is used for Parity
It allows one drive failure while data is accessing.
The data residing in failed drive can be generated from the
rest of 5 drives
Data and Parity are distributed among 6 HDDs. Since there
is no assigned disk for parity, each drive shares the same
loading in data access.
Data
Drive
All drives are used for data recording
Data is segmented and equally distributed among 6 drives.
All 6 drives will be accessed while data is read or written.
The mode provides the highest performance among all
others.
At the same time, if one drive failed, the whole data will be
lost.
Data and
Parity are
divided by
six
portions
Comparing with RAID- 5 dual parity is applied providing
even higher reliability
Allow up to two drives failure but also scarify capacity of two
drives

⑦RAID 1- 3 DRIVE MODE
⑧RAID MODE 10
⑨SINGLE DRIVE MODE
Data Drive
Data Drive
Data Drive
Only one drive is used. Data cannot be recovered if the
drive is failed
In general, Data at RAID 1 is written to two drives at the same
time and read from one or both of drives.
Capacity is half the of the total physical disk capacity
Only two drives RAID-0 mode. (The rest of four drives
cannot be used)
There is no parity so the data cannot be recovered if any of
drive fault.
Data Drive
Three drive mirroring mode. Similar to RAID MODE1, Data is
written to all of three drives and read only from one or two
drives. Even two drives failed, the data can still be accessible.
The rest of three drives cannot be used.
It is the combination of RAID-0 and RAID-1.
Performance and security can be raised.
Stripe across mirrored Drive 0, 1 and Drive 2, 3
Capacity is equal to 2 drives capacity. Data can be accessed
even one of both mirrored pair drives failed. The rest of two
drives cannot be used.
