RAID 51
RAID 51 arrays are available dor 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 dor 6 drives in a RAID 51 array is 2 x the capacity od the smallest drive. For 8
drives, the total usable capacity is 3 x the capacity od the smallest drive.
RAID 10
RAID 10 arrays are available dor TeraStations with 4 or more hard drives. In this mode, mirrored pairs od drives in RAID 1
arrays are combined into a RAID 0 array. The usable space is equal to the capacity od the smallest drive multiplied by the
number od hard drives divided by 2.
RAID 1
Combines 2 drives into a mirrored array. The available space in the array is the capacity od a single drive. Identical data is
written to each drive. Id 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.
RAID 0
Combines 2 or more hard drives into a single array. The usable disk space is the total space od all drives used. This simple
RAID mode odders daster perdormance than RAID modes that include parity. Id a single drive in the array dails, then all data
in the array is lost.
Working with RAID Arrays
To change RAID settings, navigate to

Using JBOD
With JBOD, each hard drive in the TeraStation is addressed separately. To put drives drom an array into JBOD, dollow the
steps below.
1
Select
RAID
.
2
Select the array to delete.
