2. System Setup

2.2 RAID Modes
For Raid 0/1, hard drives of identical capacities are recommended.
If the capacities are different, the total amount of the space that can be used will depend on the drive with
the smallest capacity. Under Raid 0, if one drive becomes damaged, the whole array can become
corrupted.
If only one drive is defective and the RAID mode is set to RAID 1, the data can still be accessed but we
strongly recommend replacing the faulty drive immediately to assure continued proper backup and data
safety.If more than one drive at the same time fails or if the RAID mode is set to RAID 0, the data will be
lost and the system can not be accessed again until the drive(s) have been replaced.
2.2.1 Non-RAID
The drives show up as independent volumes. Each drive can be formatted and accessed separately if one
drive fails, the other is not affected.
The setting does not provide any performance or redundancy benefits.
1. Installing hard drives for the first time or hard disk fails.
2. Turn off the power and install the hard drive(s) or replace the faulty drive(s).
3. Set the RAID switch to Non-Raid Mode.
4. Connect to your computer and turn the power on.
5. Installing new hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to create a new partition and format the drives.
6. Installing used hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to delete the old partition and format the drives.

2.2.2 RAID 0 - Disk Striping

The drives are shown as one large single volume but the total size will depend on the drive with the
smallest capacity. This setting is used where speed is the primary objective but RAID level 0 (also called
striping) is not redundant. This form of array splits each piece of data across the drives in segments; since
data is written without any form or parity data-checking, it allows for the fastest data transfer of all other
modes. On the downside, if one drive becomes damaged, the whole array can become corrupted.
1. Installing the hard drive or the hard drive fails.
2. Turn off the power and install the hard drive(s) or replace the faulty drive(s).
3. Set the RAID switch to Raid 0 Mode.
4. Connect to your computer and turn the power on.
5. Installing new hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to create a new partition and format the drives.
6. Installing used hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to delete the old partition and format the drives.

2.2.3 RAID 1 - Disk Mirroring

Two drives show up as one volume but only 50% of the total capacity, depending on the drive with the
smallest capacity, can be used. RAID 1 creates an exact copy (or mirror) of a set of data on the second
drive. This is useful when reliability and backup take precedence over storage capacity. Should one hard
drive fail, it can be replaced and the data rebuilt automatically.
1. Installing the hard drive or the hard drive fails.
2. Turn off the power and install the hard drive(s) or replace the faulty drive(s).
3. Set the RAID switch to Raid 1 Mode.
4. Connect to your computer and turn the power on.
5. Installing new hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to create a new partition and format the drives.
6. Installing used hard drives- for PC users, use the disk management tool or for Mac users, use the disk
utility to delete the old partition and format the drives.
7. The LEDs (HDD1 and HDD2) will flash rapidly when rebuilding the RAID array.
8. Rebuilding the RAID array will take several hours, depending on the drive capacity. When the data has
been restored, the LEDs will turn steady.
