Select RAID Level To ensure the best performance, you should select the optimal RAID level when you

create a system drive. The optimal RAID level for your disk array depends on a number
of factors:

• the number of drives in the disk array

• the capacity of the drives in the array

• the need for data redundancy

• the disk performance requirements

Selecting a RAID Level The factors you need to consider when selecting a RAID level are listed on the

next page.
