Cache read-ahead, also known as prefetch, allows the controller, while it is reading and copying host-requested
data blocks from disk into the cache, to copy additional data blocks into the cache. This increases the chance
that a future request for data could be fulfilled from the cache. Cache read-ahead is important for multimedia
applications that use sequential I/O.
The cache read-ahead multiplier values specify the multiplier to use to determine how many additional data blocks
are read into cache. Choosing a higher cache read-ahead multiplier may increase the cache hit percentage, however,
transfer time may also increase.
Enable and set cache read-ahead on the Logical Drive Properties dialog. See, Specifying
Logical Drive Properties.
