A method and system for reducing micro-controller access time to information stored in the remote memory via the buffer manager in a disk drive control system comprising a micro-controller, a micro-controller cache system having a plurality of line-cache segments grouped into at least one line-cache segment-group, and a buffer manager communicating with the micro-controller cache system and a remote memory. The method and system includes receiving in the micro-controller cache system a current data-request from the micro-controller, providing the current requested data to the micro-controller if the current requested data resides in a first line-cache segment of a first segment-group, and automatically filling a second line-cache segment of the first segment-group with data retrieved from the remote memory wherein the retrieved data is sequential in the remote memory to the provided current requested data.
