Abstract

A hybrid drive is disclosed comprising a head actuated over a disk, and a non-volatile semiconductor memory (NVSM). Access commands are received from a host including disk read commands. When a high workload of disk access commands is detected, data of at least one disk read command is migrated to the NVSM.
