ABSTRACT:
Herein described is at least a method and system for improving the performance of a disk drive. A cache work queue and a disk work queue operate together as a dual work queue to facilitate efficient processing of one or more read/write operations performed by the disk drive. In a representative embodiment, the disk drive controller comprises a host interface, a cache buffer, and a disk drive media interface. The disk drive controller comprises the necessary circuitry to execute one or more host commands provided by a host computer. Further, the disk drive controller may facilitate the generation of the cache work queue and the disk work queue. The disk drive controller executes one or more host commands that are received through the host interface such that the cache work queue and disk work queue are employed when a read or write operation is performed.
