Wake-ahead based on patterns

A device comprising:

• a processor to:
• request a predictive hard disk drive operation;
• weigh a performance improvement associated with the hard disk drive if the predictive hard disk drive operation is granted against a life of the hard disk drive if the predictive hard disk drive operation is not granted;
• bypass the predictive hard disk drive operation if the life of the hard disk drive outweighs the performance improvement;
• and
• operate the hard disk drive in accordance with the predictive hard disk drive operation if the performance improvement outweighs the life of the hard disk drive.

A method comprising:

• detecting an event;
• determining whether the event correlates to access of a hard disk drive;
• requesting a wake-ahead of the hard disk drive when the event correlates to access of the hard disk drive;
• weighing a performance improvement 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.

A computer-readable memory device having stored thereon instructions, executable by at least one processor, the computer-readable memory device comprising:

• one or more instructions to detect an event;
• one or more instructions to determine whether the event correlates to access of a hard disk drive;
• one or more instructions to request a predictive hard disk drive operation when the event correlates to access of the hard disk drive;
• one or more instructions to weigh a performance improvement if the predictive hard disk drive operation is granted against a life of the hard disk drive if the predictive hard disk drive operation is not granted;
• and
• one or more instructions to perform the predictive hard disk drive operation if the performance improvement outweighs the life of the hard disk drive.
