摘要:
A hybrid drive is disclosed comprising a disk channel including a head actuated over a disk, the disk comprising a plurality of data sectors, and a non-volatile semiconductor memory (NVSM) comprising a plurality of memory segments. Write commands are received from a host, wherein the write commands comprise write data. When a frequency of the write data exceeds a threshold, an operating mode of the disk channel is changed to change a power consumption rate of the disk channel.
