Claim:
1. A method comprising: assigning one of multiple priority levels to groups of data accessed by issuing one or more input/output (I/O) commands to a hybrid drive while a computing device is operating in a power saving mode, the hybrid drive including both a performance part and a base part in which groups of data can be stored, the one of the multiple priority levels comprising a priority level that is at least a lowest priority level of the multiple priority levels to reduce accesses to the base part while the computing device is operating in the power saving mode, the lowest priority level being assigned to a particular group of data so that an amount of data at the lowest priority level in the performance part of the hybrid is greater than an amount of data in at least one other of the multiple priority levels, the lowest priority level being a basis for transferring the particular group of data between the performance part and the base part of the hybrid drive, and the assigning the one of the multiple priority levels being based at least in part on whether the one or more I/O commands to the hybrid drive are associated with a read request or a write request; and communicating, to the hybrid drive, an indication of the assigned one of the multiple priority levels of the groups of data accessed by issuing one or more I/O commands to the hybrid drive while the computing device is in the power saving mode.
