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
