tip: writing to the disk cache during renders through the render queue:
http://adobe.ly/1zxe0Sd
"[T]ry enabling the disk cache in the render queue by changing the Disk Cache setting in the Render Settings dialog box to Current Settings, rather than Read Only. You may want to even go so far as to edit your render settings templates to make this change, as I have done with mine.... With the Disk Cache value in the render settings set to Current Settings, the disk cache will be written to during renders through the render queue as long as you have Enable Disk Cache checked in the Media & Disk Cache preferences."
