RAID Modes
The TeraStation supports many types of RAID. The type of RAID arrays available for use depends on how many drives
are installed on 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
Dashboard in Settings and NAS Navigator2 will change from
I46
or
I47
to
I18
.
• RAID 5, 6, and 10 are only available for TeraStation models that allow three or more drives to be inserted. Please
check Settings on your model before changing the RAID mode.
RAID 6
RAID 6 arrays are available for TeraStations with four 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 become damaged, you can recover data by replacing them. If three or more drives become damaged,
then all data in the array will be 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 becomes damaged, you can recover data by replacing the damaged drive. If two or more drives become
damaged at the same time, then all data in the array will be lost.
RAID 10
RAID 10 arrays are available for TeraStations with four 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.
