Caution: When caching is Enabled, there is a risk of data
loss or corruption during a power failure. Therefore you
should enable caching unless your data is highly sensitive,
or your application performs completely reads.

(DMA) mode for the drive. Enabled provides maximum
performance. Default is Yes to enable.
SMART—Enables or disables the predictive failure feature of
the disk drive. When enabled the SMART status of the drive
(Healthy or Failed) will be displayed along with the physical
drive display during POST. If the drive does not support
SMART, the SMART status is not displayed. Default is Yes to
enable.
Allow Read Ahead—Enables or disables the read ahead cache
