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, and
•
the disk performance requirements.
