Abstract
Adaptive power management for a data storage device (DSD). A command rate is determined for service requests received by the DSD and a latency is determined for the DSD in performing service requests. The command rate and the latency are used to determine a probability of receiving no service requests within a time interval and power states of the DSD are managed based on the probability of receiving no service requests.
