Summary of the RAID 5 function (Redundant

Arrays for Independent Disks, independent

data disks with distributed parity blocks)

It is possible to use the RAID 5 function with an optional

extension unit.

RAID level 5 regards 3 or more drives as one drive, and it is

possible to read data by attaching error correction data

even though one of the drives is broken automatically. (It is

impossible to recover data if two drives are simultaneously

damaged or the second drive fails during the data recovery

process.)

RAID level 5 requires a minimum of 3 drives to implement.

When using the RAID function, the logical disk size of the

extension unit will be as below.

Logical disk size = Smallest size of the disk among the

disks in the extension unit x (Number of the disks in the

extension unit - 1)

Note:

Depending on the model of a hard disk drive, the

logical disk size may be a few percent smaller than the

size resulting from the formula above.

Important:

•

When connecting two extension units or more with this

unit, it is impossible to connect the extension unit with

the RAID 5 function and the one without the RAID 5

function at the same time.

•

When the RAID 5 function is used, it is impossible to

use two hard disks in this unit. The recorded pictures in

those disks will not be deleted.
