Controllers 75
• Read Cache Enabled —When the read cache is enabled, the controller
reads the cache information to see if the requested data is available in the
cache before retrieving the data from the disk. Reading the cache
information first can provide faster read performance because the data (if
available in the cache) can more quickly be retrieved from the cache than
from the disk.
•
Read Cache Disabled —When the read cache is disabled, the controller
retrieves data directly from the disk and not from the cache.
