A method, which may be embodied upon a computer readable medium and executed by a processor, for dynamically adjusting buffer utilization ratios for a hard disk drive system. The method establishes and dynamically adjusts a host transfer goal, which targets the amount of data transferred between host catch-up conditions for a current command. The actual amount of data transferred between host catch-up conditions is compared against the host transfer goal, and the buffer utilization ratios are adjusted when the actual amount of transferred data does not exceed the transfer goal. The host transfer goal is established by a number of operational characteristics, including drive transfer speed, host transfer speed, and track switch locations.
