RAID Levels
Below is the list of RAID Levels available for configuration in the NAS.
RAID Level
No. of Allowed
Failed Drives
Description Min. Required No. of Drives
0
None
Block striping is provided and yields higher performance than with individual drives. There
is no redundancy.
1
1
1
Drives are mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant.
2
5
1
Data is striped across several physical drives. Parity protection is used for data
redundancy.
3
6
2
Data is striped across several physical drives, just like in RAID 5, and a second set of parity
is calculated and written across all the drives. RAID 6 provides for an extremely high data
fault tolerance and can sustain multiple simultaneous drive failures.
4
10
2
Striping over two RAID1 RAID sets. This level provides mirroring and redundancy through
striping.
4
Linear
(JBOD)
None
Linear (JBOD) is similar to RAID 0 in that it concatenates the capacity of all member drives.
The data is written linearly starting with the first disk drive. When first disk drive becomes
full, the next disk drive is used. Linear can have 1 or more disk drives. There is no data
redundancy.
