摘要： A host device and a storage device with a Serial ATA (SATA) architecture to independently transition to a deeper low power state after first entering an initial low power state without first transitioning to the Active state. The transition from the Partial state to the Slumber state is direct and the transition may be enabled, but not negotiated through a handshaking process.

摘要： A method and apparatus for detecting a presence of a fail over switch is described. In one embodiment, during an Serial ATA sequence initialization handshake, a host transmits a COMRESET to a device. In return, the host receives a COMWAKE from the device. If the host is of a first type of host, then the host identifies a presence of a fail over switch, in response to receipt of the COMWAKE. If the host is of a second type of host, then the host ignores the COMWAKE. The host then receives a COMINIT from the device, in accordance with the Serial ATA sequence handshake. The host transmits a COMWAKE to the device, and the host receives a COMWAKE in return from the device.

摘要： A method and apparatus for reducing the disk drive data transfer interrupt service latency penalty is described. The method comprises beginning a data transfer between a disk drive and a host system, issuing an interrupt before the transfer is complete, and then completing the data transfer. This method may be implemented on a computer assembly that includes a processor, an input/output controller, and a scatter/gather list, which is stored in memory, that includes an entry that will cause the input/output controller to generate the interrupt.

摘要： A mass storage device such as a disk drive or SSD (solid state drive) employs optimization logic for reduced power consumption in a host personal electronic device that identifies and prioritizes performance and power trade-offs by considering user expectations, user presence and application responsiveness. The storage device receives commands and information from the host device indicative of user expectations about application invocation, data freshness, and usage patterns, and determines a operational state indicative of behavior settings for reducing power consumption while maintaining the performance constraints required by the user expectations. The granularity of performance considerations communicated from the host device to the mass storage device is expanded to permit the storage device to determine, based on performance constraints from user expectations, appropriate and specific power reduction measures for maintaining the user experience.
