<h2>read-ahead cache mode - Disabled</h2>

<p>An option of the read-ahead cache mode. When the read-ahead cache mode is disabled,
  the controller transfers data from the logical device to its local
  cache in increments equal to the system I/O request size. This optimizes performance
  when the workload is random or the system I/O requests are smaller than the
  stripe size.</p>
