3 RAID Levels

There are six official RAID levels (RAID 0 through RAID 5). MegaRAID supports RAID levels 0,

1, 3, and 5. LSI Logic has designed three additional RAID levels (10, 30, and 50) that provide

additional benefits.

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

The factors you need to consider when selecting a RAID level are listed on the next page.
