摘要： A data storage system including a plurality of storage devices, each of the storage devices in the plurality of storage devices comprising a plurality of logical block addresses (“LBAs”) and configured to be in a first operating mode or a second operating mode, wherein the second operating mode comprises a reduced power mode relative to the first operating mode, and a bridge configured to be connected to the plurality of storage devices and a host configured to transmit a host command to access an LBA. The bridge is configured to receive the host command to access the LBA, determine a storage device in the plurality of storage devices where the LBA is located, and indicate only to the storage device where the LBA is located, that the storage device where the LBA is located should transition from the second operating mode to the first operating mode.

摘要： A data storage device including a solid state memory comprising logical block addresses (“LBAs”) corresponding to boot data accessed by a host during a boot process, and a controller. The controller can be configured to determine the LBAs corresponding to the boot data, and determine whether the solid state memory has reached an end-of-life condition. Upon determining that solid state memory has reached an end-of-life condition, the controller can restrict the host to write to the LBAs corresponding to the boot data during a boot process, and set the solid state memory into a read only mode when the boot process is complete.

摘要： A storage device including a first storage unit including a first media of a first type, a second storage unit including a second media of a second type, and a controller. The controller initializes the storage device for a host by receiving an initialization query from the host, identifying, to the host, that the storage device comprises the second storage unit but not the first storage unit, receiving an indication from the host indicating that the host is compatible with the first storage unit, and identifying, to the host, that the storage device comprises the first storage unit and the second storage unit. The host initializes the storage device by initializing the second storage unit, transmitting the indication to the controller indicating that the host is compatible with the first storage unit, receiving the identification of the first storage unit from the controller, and initializing the first storage unit.

摘要： A combination of a host system and a storage system is disclosed that facilitates improved responsiveness of the host system to user requests. In one embodiment, the host system includes a cache management module, a partitioning module, and a driver. The cache management module determines write data to cache to a dedicated zone of a hard disk media of the storage system. The partitioning module partitions the hard disk media into one partition including the dedicated zone and another partition not including the dedicated zone. The driver transmits storage access commands to the storage system to cache data in and retrieve cached data from the one partition. Thereby, the host system can access the write data from the hard disk media more quickly than if the write data were cached in and accessed from another zone of the hard disk media.

摘要： A storage device including a non-volatile memory configured to store data from a host, and a controller. The controller is configured to detect when the host is in a low power periodic update mode, the detecting based at least on part on a timing of a communication from the host, and place the storage device in a power up in standby mode when the host is in the low power periodic update mode.
