Creates two separate volumes (or one volume if

only one hard drive is present). Each hard drive

has its own volume.

Combines both hard drives in a linear fashion

which will create one large volume geared towards

maximum available space.

Combines both hard drives in a striped fashion

which will create one large volume geared towards

maximum performance.

Mirrors the hard drives for redundancy. If one

hard drive fails, the other still has all of the data.

Replace the failed hard drive and it will re-mirror,

restoring maximum data protection.

Standard:

JBOD (Linear):

RAID 0:

RAID 1:

In this section, you may configure your hard drives by clicking the

Set RAID Type and Re-Format

What is RAID?

RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing

fault tolerance and improving performance.

There are several different levels of RAID, with each providing a different

method of sharing or distributing data amongst the drives. The NVR supports RAID levels 0 and 1.

RAID 0

RAID 0 provides

data striping

, which spreads

out blocks of data over both drives, but does

not provide data redundancy.

Although performance is improved, the lack of

fault tolerance means that if one drive fails, all

data in the array will be lost.

RAID 0

RAID 1

RAID 1 provides

mirroring

over both disks, with

the same read/write speed of a single disk.

A

RAID 1 array can only be as large as its smallest

member disk.

Because the data is stored on both disks,

RAID 1 provides fault tolerance and protection,

in addition to performance advantages.
