Abstract:
A background operation is internally triggered by firmware of a disk drive. During a training phase defined by a first time period, access latency of host commands is monitored during rotational position sorting command selection. During a sorting phase after the training phase, a sorting threshold is defined based on the access latencies measured during the training phase. The background command is selected for execution in the sorting phase if the seek and rotational latency is less than the sorting threshold.
