1.3 RAID Mode Explanation

Drive counts from

0 to 5

● Any change of RAID mode will result in data rebuild and data lost.

①

RAID MODE 6

②

RAID MODE 0

③

RAID MODE 3

④

RAID MODE 5

Drive

Parity Data
Drive

Data and
parity are
equally
distributed
among 5
drives

The most bottom drive is reserved for future usage. One

Parity drive is located at Drive 4.

It allows one drive failure while data is accessing.

The data residing in failed drive can be generated from the

rest of 4 drives

The most bottom drive is reserved for future usage. Data

and Parity are distributed among 5 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

sacrifice capacity of two drives

CAUTION
