array. The usable space is equal to the sum of the capacity of the hard drives minus the capacity of one drive. For
example, if 4 drives are combined into a RAID 5 array, the usable space is the sum of 3 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 51
**
RAID 51 arrays are available for TeraStations with 6 or more hard drives. In this mode, two RAID 5 arrays are combined
into a RAID 1 array. The total usable space for 6 drives in a RAID 51 array is 2 x the capacity of the smallest drive. For 8
drives, the total usable capacity is 3 x the capacity of the smallest drive.

RAID 50

RAID 50 arrays are available for TeraStations with 6 or more hard drives. In this mode, two RAID 5 arrays are combined
into a RAID 0 array. The total usable space for 6 drives in a RAID 50 array is equal to 4 x the capacity of the smallest drive.

RAID 10
*
RAID 10 arrays are available for TeraStations with 4 or more hard 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 hard drives divided by 2.

number of hard drives divided by 2.
RAID 1
Combines 2 drives into a mirrored array. The available space in the array is the capacity of a single drive. Identical data is
written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive. As long as one drive
in the array remains undamaged, all data in the array can be recovered.

in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines 2 or more hard drives into a single array. The usable disk space is the total space of all drives used. This simple
RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data
in the array is lost.

JBOD
This mode uses the hard drives inside the TeraStation as individual drives. The disk space you can use is the total
capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.
