Normal The controller does not use read-ahead for the selected
logical drive. This is the default setting.
Read Ahead The controller uses read-ahead for the selected logical drive.
Adaptive Read Ahead The controller uses read-ahead if the two continuous disk

are random, the controller does not use read-ahead.
However, all requests are still evaluated for possible
sequential operation.
