ABSTRACT:
A method may include detecting an event, determining whether the event correlates to a hard disk access, requesting a wake-ahead of a hard disk drive if it is determined that the event correlates to a hard disk access, weighing a performance improvement of the hard disk drive if the wake ahead request is granted against a life of the hard disk drive if the wake ahead request is not granted, and waking ahead the hard disk drive if the performance improvement outweighs the life of the hard disk drive.
