When you create logical drives in Adaptec Storage Manager, 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 chapter provides a comparison of all the RAID levels supported by Adaptec Storage
Manager, and provides a basic overview of each to help you select the best level of protection
for your storage system.
