The LaCie professional DAS prioritizes background activities based on the specified control rates. When background activities are in progress, the device is still available to the operating system for normal operations. However, the response time may be slower depending on the background activity control rate.

The rate of various background activities can be modified from the Property tab for the Adapter. Move the slider to adjust the rates and choose Modify to confirm the changes.

The choice between protection and performance can vary with projects. To accommodate such changes, the cache mode for a virtual disk can be modified from the Property tab for the virtual disk. Select between the options and choose Modify to confirm changes.

To view the properties of an array, virtual disk, or physical disk, select the item in the Storage pane. The Property tab gives you all the pertinent details.
