Abstract
A hybrid drive includes multiple parts: a performance part (e.g., a flash memory device) and a base part (e.g., a magnetic or other rotational 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. The drive access system supports multiple priority levels and obtains priority levels for groups of data identified by logical block addresses (LBAs). The LBAs read while the device is operating in a power saving mode are assigned a priority level that is at least the lowest of the multiple priority levels supported by the device, increasing the likelihood that LBAs read while the device is operating in the power saving mode are stored in the performance part of the hybrid drive.
