A common thing to do is to disable the read cache and only enable
write caching for your container.

CLI > open aac0
Executing: open "aac0"

AAC0> container show cache 0
Executing: container show cache 0

Global Container Read Cache Size  : 0
Global Container Write Cache Size : 16203776

Read Cache Setting        : DISABLE
Write Cache Setting       : ENABLE ALWAYS
Write Cache Status        : Active, not protected, battery not present 

Hope this helps.
