摘要： A method for determining an aging period for retaining a write-back data in a cache memory prior to writing the write-back data to a storage media is determined through use of a write-back aging routine. The aging period is based on a proportional utilization level of the cache memory by the write-back data, the higher the memory utilization level, the shorter the period for aging the write-back data. The aging period takes a form of an aging threshold, which differs depending on the memory utilization level, i.e., the amount of cache memory utilized by the write-back data.The method includes, identifying the memory utilization level, selecting the data aging threshold based on the memory utilization level; and writing the data from the cache memory to the storage media when an age of the data in the memory exceeds the selected data aging threshold.

摘要： A method for improving throughput performance of a data storage device by executing an execution critical write-back data priority routine programmed into a controller of the data storage device. The method includes, determining a write-back data aging threshold limit; identifying and executing a pending command; recognizing write-back data exceeding the aging threshold limit as an ending position aged data execution command; determining a read/write head following an execution of a pending command; determining a latency portion of the aged data execution command based on the determined head position; ascertaining a total execution time for each of a plurality of commands based on the determined head position; selecting from the plurality of commands an additional command executable within the determined latency portion; and executing both the additional command and the aged data execution command following execution of the pending command, when the total execution time of the aged data execution command is unaffected.
