Chapter 4 Storage Management

RAID Modes

TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are
installed in your TeraStation.

Notes:

• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter.

Always back up any important data before performing actions that affect your RAID array.

• Some RAID arrays allow you to change the RAID mode without losing data by adding drives. To change a RAID

mode by adding drives to the existing array, refer to the

“Expanding RAID Capacity Without Deleting Data”

section

below.

• Drive capacity is displayed in Settings in actual gigabytes. The Properties window in Windows may show GiB

instead, which will be a smaller number.

• If the TeraStation is restarted or shut down while changing the RAID mode, the message that appears on the LCD

panel will change from I46 or I47 to I18.

• RAID 5, 6, or 10 are only available for TeraStations with three or more drives inserted. Please check Settings on

your model before changing the RAID mode.

RAID 6

RAID 6 arrays are available for TeraStations with four or more drives. RAID 6 combines four or more drives into a
single array. The usable space is equal to the sum of the capacity of all drives minus the capacity of two drives. For
example, if four drives are combined into a RAID 6 array, the usable space is the sum of the capacity of two drives. If
two drives in the array are damaged, you can recover data by replacing them. If three or more drives are damaged,
your data is lost.

RAID 5

RAID 5 arrays are available for TeraStations with three or more drives. RAID 5 combines three or more drives into a
single array. The usable space is equal to the sum of the capacity of the drives minus the capacity of one drive. For
example, if four drives are combined into a RAID 5 array, the usable space is the sum of three drives. If one drive in
the array is damaged, you can recover data by replacing the damaged drive. If two or more drives are damaged at
the same time, your data is lost.

RAID 10

RAID 10 arrays are available for TeraStations with four or more drives. In this mode, mirrored pairs of drives in RAID 1
arrays are combined into a RAID 0 array. The usable space is equal to the capacity of the smallest drive multiplied by
the number of drives divided by two.
