Chapter 3 RAID Modes and Drive
Management
Available RAID Modes
The LinkStation supports multiple types of RAID. The type of RAID arrays available for use depends on how many
drives are installed on your LinkStation.
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 arrays will 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
“Changing the RAID Mode using RMM”
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.
• After the RAID mode is changed (except when creating a RAID 0 array), the LinkStation performs a RAID scan that
will take about 10 hours per TB. File transfers are slower during this period. While the
I17
message is displayed in
NAS Navigator2, do not turn off the LinkStation. If you do, the RAID scan will start over.
JBOD
This mode uses the drives inside the LinkStation as individual drives. The usable space is equal to the total capacity
of both drives on the LinkStation. If any of the drives fail, then all data on that drive will be lost.
RAID 1
Combines two drives into a mirrored array. The usable space is equal to the capacity of a single drive. Identical data
is written to each drive. If a drive fails, data can be recovered by replacing the failed drive. As long as one drive in the
array remains undamaged, all data in the array can be recovered.
RAID 0
Combines two drives into a single array. The usable space is equal to the total capacity of both drives in the array. If a
single drive in the array fails, then all data in the array will be lost.
The default RAID mode for LS220D and LS220DR LinkStation models is RAID 1.
Working with RAID Arrays
To change RAID settings, navigate to
Drives
>
RAID
in Advanced Settings.
Using JBOD
With JBOD, each drive on the LinkStation is addressed separately. To put drives in an array into JBOD, follow the
procedure below.
