The use of multiple drives improves the rebuild process, which is up to 10 times faster than traditional RAID. This speed is even more important when you use large drives. 

The conversion from traditional RAID to distributed RAID is possible by using volume mirroring or volume migration. Mixing traditional RAID and distributed RAID in the same storage pool is also possible. 

## Example 

The same number of disks can be configured by using traditional or distributed RAID. In our example, we use six disk drives and assign those disks as RAID 6 to a single pool. 

Figure 4-49 shows the setup for a traditional RAID 6 environment. The pool consists of one MDisk, with five disk drives. The spare drive is not listed in this summary.
