| RAID Setup |
Note: Changing the RAID setup will require you to re-format the drives. Make sure you backup all data before doing so! |
|
BIG
1-4 Hard Drives
|
JBOD (spanning)
The drives show up as one large single volume. Spanning is an array (not RAID) that is written sequentially across the drives. By itself, it does not provide any performance or redundancy benefits. Use this if you have installed 1-4 hard drives with different capacities. |
|
FAST *
4 Hard Drives
|
RAID 0 (striping+striping)
The drives show up as one large single volume. This mode requires 4 identical drives to implement. Used where speed is the primary objective, 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 of parity data-checking, it allows for the fastest data transfer of all other modes. However, if one drive becomes damaged, the whole array can become corrupted. |
|
SAFE *
2 or 4 Hard Drives
|
RAID 1 (mirroring)
The drives show up as two volumes, each representing one set. This mode requires 1 or 2 sets of 2 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data on the second drive. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will be 50% of the total capacity for each set but when one hard drive fails, it can be replaced and the data rebuilt automatically. |
|
SAFE II *
4 Hard Drives
|
RAID 10 (mirroring+striping)
The drives show up as one single volume. This mode requires 4 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will only be as large as 50% of the total capacity of all drives combined but when one hard drive fails, it can be replaced and the data rebuilt automatically. |
| Remarks |
* For the FAST and SAFE mode, hard drives of identical capacities are recommended! If the capacity is different, the total amount of the space that can be used will depend on the drive with the smallest capacity. |
