ReadyNAS OS 6.0

RAID 5. This RAID level also provides data redundancy, but it requires at least three disks. RAID 5 uses the capacity of one disk to protect you from data loss if one disk fails. Your data is distributed across multiple disks to improve disk performance. The total capacity of your storage system equals the capacity of all your disks minus the capacity of one disk. It is supported on systems with at least four drive bays.

RAID 6. This RAID level can recover from the loss of two disks. Your data is distributed across multiple disks to improve disk performance. The total capacity of your storage system equals the capacity of all your disks minus the capacity of two disks. It is supported on systems with at least four drive bays.

RAID 10 (or 1+0). This RAID level uses both RAID 1 and RAID 0 technology. First, your data is duplicated so that exactly the same data is stored on two or more disks. Then, the data is distributed across additional disks to improve disk performance. It is supported on systems with at least four drive bays.

The Flex-RAID levels that you can select depend on the number of disks included in the volume. The following table describes the Flex-RAID levels that are available for a given number of disks. It also indicates whether adding a disk for data protection is possible for each configuration.

Can I add a disk to for data protection?

per Volume

 

 

 

 

 

1

RAID 1

Yes. (Additional disk provides redundancy.)

 

 

 

2

RAID 1

No. (Volume protection is already redundant.)

 

 

 

2 or more

RAID 0

No. (RAID 0 does not offer protection.)

 

 

 

3 or more

RAID 5

Yes. (Additional disk provides dual redundancy and converts the volume to
