Abstract
A hybrid drive includes multiple parts: a performance part (e.g., a flash memory device) and a base part (e.g., a hard disk drive). A drive access system, which is typically part of an operating system of a computing device, issues input/output (I/O) commands to the hybrid drive to store data to and retrieve data from the hybrid drive. Some data can be stored in one part but not the other, and this data can be synchronized with (e.g., copied to) the other part at various times. The drive access system provides indications to the hybrid drive of when to synchronize data in one part with the other part. These indications are made so that potential interference with use of the device by the user and/or power saving modes of the device due to the synchronization is reduced.
