Abstract
A hybrid drive is disclosed comprising a head actuated over a disk, and a non-volatile semiconductor memory (NVSM) operable to cache data. When beginning to spin up the hybrid drive, a first spin-up profile is used while servicing access commands using the NVSM, including write commands and read commands. When a cache event occurs, spinning up the disk is finished using a second spin-up profile in order to spin-up the disk faster.
