Abstract
A hybrid drive is disclosed comprising a head actuated over a disk comprising a plurality of data sectors, and a non-volatile semiconductor memory (NVSM) comprising a plurality of memory segments. A logical block address (LBA) is mapped to a data sector on the disk. During a bias interval following the start of a host boot operation, a biased migration policy is executed that increases a likelihood of migrating the LBA to the NVSM. After the bias interval a normal migration policy is executed.
