When the write cache is enabled, data is stored locally on the controller before it is written to disk, allowing the computer to continue with its next task.

For details, see "Enabling and Disabling the Unit Write Cache" on page 118. This feature interacts with functionality of the BBU, if you have one, and with the unit's StorSave profile.
