How do I change the RAID mode to RAID5 (3 hard drives) on my hard drive?
Several RAID modes are available for LinkStation models with multiple hard drives. LinkStation with only one hard drive does not support RAID modes.
By default, RAID mode is set to RAID0.
If you change the mode, follow the steps below.
All data is lost when the RAID mode is changed. Back up any important data before changing RAID modes.
•RAID 5 mode (3 hard drives):
RAID 5 mode (3 hard drives) is available for Linkstation models with more than 3 hard drives. Uses 3 hard drives as one array. It generates parity during writes, so access speeds are slower than other RAID modes. Usable space is the sum of 2 hard drives' space. If one hard drive in the array is damaged, you can recover data by replacing the hard drive. You can not recover data if 2 or more drives are damaged.
- Change system to normal mode.
Click here for how to setup for Normal mode.
- Click [System]-[Storage]-[RAID array] on setting screen of LinkStation.
- Click the array you want to configure.
- Select hard drives (all 4 of them) to use in RAID 5.
(1) Select [raid5].
(2) Click [Create RAID Array].
While the array is being built, the file transfer speed will be slower than usual for hours. It will take about 6 hours for a 1 TB RAID array. The Info/Error LED or the Power LED will blink amber while the array is being built. Do not turn OFF the LinkStation while the RAID array is being built.
- The [Confirm Operation] screen will appear. Enter the number shown in the [Confirmation Number] field within 60 seconds, and then click [Apply].
- Follow the instructions displayed on the screen.
When the build finishes, the LED will stop blinking. You have set up a RAID 5 array.
|RMM(RAID Mode Manager) and EDP(Easy Data Protection) function:
With RMM or EDP function, you can create or expand a RAID1 or RAID5 array without erasing the data on the drives if it meets below conditions. More than 3 hard drives are necessary for RAID5.
