4. RAID Configuration

This section provides information on configuring RAID settings.

Supported RAID Types

QNAP drive adapters support several RAID types.

Important

• When disks with different capacities are combined in one RAID group, all disks

function according to the capacity of the smallest disk.

• You can only use one disk type (HDD or SSD) in a RAID group. Combining different

types of disk in one RAID group is not supported.

RAID Type

Number of Disks

Description

JBOD (Just a Bunch
of Disks)

2

• JBOD combines disks together in a linear fashion. The

system writes data to a disk until it is full, and then
writes to the next disk.

• JBOD allows all of the disks capacity to be used, but

does not provide any disk failure protection or
performance benefits.

• Unless you have a specific reason to use JBOD, use

RAID 0 instead.

RAID 0

2

• Disks are combined together using striping.

• RAID 0 offers the fastest read/write speeds and uses

the total capacity of all the disks.

• RAID 0 provides no disk failure protection. This RAID

type must be paired with a data backup plan.

• RAID 0 is recommended for high performance

applications such as video editing.

RAID 1

2

• An identical copy of data is stored on two disks. If either

disk fails, data can still be read from the other disk.

• Half of the total disk capacity is lost, in return for a high

level of data protection.

• RAID 1 is recommended if you have two disks.
