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
also vary by the number of disk drives they support.
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.
