Problems solved by technology

One such problem is that it remains difficult to determine which data is to be stored on the flash memory drive of the hybrid drive
Poor determination of what data to store on a flash memory drive can result in a hybrid drive with little, if any, performance improvement over a traditional magnetic media hard drive, leading users to Disappointed by high cost and lack of performance improvements

Embodiment Construction

[0014] This article discusses power save mode hybrid drive access management. A hybrid drive consists of multiple parts: a performance part (eg, a flash memory device) and a base part (eg, a hard drive). A drive access system (usually part of a computing device's operating system) issues input / output (I / O) commands to the hybrid drive to store and retrieve data to and from the hybrid drive. The drive access system supports multiple priority levels, and obtains the priority level of a data group identified by a logical block address (LBA). With each I / O command, the drive access system may include an indication of the priority level of the LBA(s) associated with that I / O command. The hybrid drive determines which LBAs are to be stored on which portion or portions of the hybrid drive based at least in part on the priority level indication received from the drive access system.

[0015] A record of LBAs accessed is maintained while the device implementing the drive access syste...

Abstract

A hybrid drive consists of multiple parts: a performance part (eg, a flash memory device) and a base part (eg, a magnetic or other spinning disk drive). A drive access system, typically part of a computing device's operating system, 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 the priority level for a data group identified by a logical block address (LBA). The LBA read while the device is operating in the power saving mode is assigned at least the priority level as the lowest priority level among the plurality of priority levels supported by the device, thereby increasing the priority level when the device is operating in the power saving mode Possibility that the read LBA is stored in the performance part of the hybrid drive.

Description

Background technique [0001] Computers traditionally have storage devices on which data such as program instructions and user data may be stored. As technology has advanced, these storage devices have included magnetic floppy disks, magnetic hard disks, solid state drives (eg, flash memory drives), and others. Some hybrid drives have also been developed that include larger capacity (but less expensive) hard disk drives and smaller capacity (but more expensive) flash memory drives. While such hybrid drives may be beneficial, they are not without their problems. One such problem is that it remains difficult to determine which data is to be stored on the flash memory drive of a hybrid drive. Poor determination of what data to store on a flash memory drive can result in a hybrid drive with little, if any, performance improvement over a traditional magnetic media hard drive, leading users to High cost but still disappointed by lack of performance improvements.
