Chapter 5 Disk Manager
Disk Manager is an application that manages RAID arrays and internal or external drives. To open Disk Manager, click
the icon on the home screen.
RAID Arrays
RAID 1
Combines 2 drives from drives into a mirrored RAID array. The available space in the array is the capacity of a single
drive. Identical data is written to each drive. If a drive becomes 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 drives into a single RAID array. The available space is the total capacity 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.
Linear
Combines all drives from drives into a single virtual drive. For this virtual drive, data will be written onto the first
drive, then to the next drive when the first drive becomes full, and so on. The available space is the total capacity of
all drives used. Linear mode offers no redundancy. If any drive becomes damaged, data on the drive will be lost.
JBOD
This mode uses the drives inside the LinkStation as individual drives. The available space is the total of all drives in
the LinkStation. If any drive becomes damaged, then the data on that drive is lost.
Working with RAID Arrays
Note: 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.
Using JBOD
With JBOD, each drive in the LinkStation is addressed separately. To put drives from an array into JBOD mode, follow
the procedure below.
