Created 04/03/2013 18:25  |   Updated 11/07/2013 11:59

TeraStation supports many types of RAID. The type of volumes available for use depends on how many drives are installed in your TeraStation.

RAID 5 Volume

Mirrored Volume (RAID 1)

Striped Volume (RAID 0)

Spanned Volume

Simple Volume (JBOD)

Note:
By default, drive C is a mirrored array using drives 1 and 2, and drive D is a RAID 5 array using all drives*.

* For WS-WVL TeraStation, drive D is a mirrored array using drives 1 and 2.

 

 

RAID 5 Volume

The unallocated areas of three or more hard drives are used as a single array. If one drive in a RAID 5 array fails, data on the array can be recovered after the failed drive is replaced. However, if two or more drives are damaged at the same time, your data is lost.

 

Mirrored Volume (RAID 1)

The unallocated areas of two drives are combined into a single RAID 1 array. 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.

 

Striped Volume (RAID 0)

The unallocated areas of two or more drives are combined into a single RAID 0 array. If a single drive in the array fails, then all data in the array is lost.

 

Spanned Volume

The unallocated areas of multiple hard drives are joined to create a single logical volume. This allows various drive spaces to be combined efficiently. If even a single drive is damaged, your data is lost.

 

Simple Volume (JBOD)

This mode uses the hard drives inside the TeraStation as individual drives. If any drive is damaged, then the data on that drive is lost.
