When you create arrays (or logical drives), you can assign a RAID level to protect your data.

Each RAID level offers a unique combination of performance and redundancy. RAID levels

This appendix describes the RAID levels supported by your HostRAID controller, and provides
a basic overview of each to help you select the best level of protection for your data storage.
