    Abstract: Method and apparatus for distributing wear in a data storage system. In some embodiments, a first data transducer is used to record data to a first data recording surface. Performance statistics are accumulated including a dwell metric value indicative of relative dwell time of the first transducer adjacent a selected radial location on the first data recording surface and an operational life metric value indicative of accumulated elapsed operation of the first transducer. A data migration mode is enacted to migrate data from the selected radial location to a local memory in a hierarchical memory structure responsive to at least a selected one of the dwell metric value or the operational life metric value. Host access commands are temporarily serviced from the local memory, after which the data are returned to the selected radial location or a new location in a disc stack main memory store.

    Abstract: A data storage system includes data storage and random access memory. A sorting module is communicatively coupled to the random access memory and sorts data blocks of write data received in the random access memory of the data storage. A storage controller is communicatively coupled to the random access memory and the data storage and being configured to write the sorted data blocks into one or more individually-sorted granules in a granule storage area of the data storage, wherein each granule is dynamically constrained to a subset of logical block addresses. A method and processor-implemented process provide for sorting data blocks of write data received in random access memory of data storage. The method and processor-implemented process write the sorted data blocks into one or more individually-sorted granules in a granule storage area of the data storage, wherein each granule is dynamically constrained to a subset of logical block addresses.

    Abstract: Systems and methods are disclosed for electronic device power consumption grading. In some examples, similar electronic devices may consume different amounts of power due to variations in components of the electronic devices. The components can include electrical components (e.g., discrete circuits, integrated circuits, etc.), mechanical components (e.g., motors, traces, etc.), electro-mechanical components (e.g., switches, motors, piezoelectric devices, etc.). Power consumption information for specific components can be determined and a power consumption grading for the specific electronic device can be determined from the power consumption information. A user may then utilize the power consumption grading to optimize a usage of the electronic device.

    Abstract: A data storage device includes at least one data storage disc having at least one data storage surface, and at least one read head configured to communicate with the at least one data storage surface. The data storage device also includes a controller communicatively coupled to the at least one read head. The controller is configured to determine a fly height for the at least one read head over the at least one data storage surface as a function of a read workload associated with the at least one data storage surface or as a function of an ability to satisfy a read request to the at least one data storage surface on a first read attempt.

    Abstract: A data storage device includes at least one data storage medium having a plurality of tracks. The data storage device also includes at least one actuator that supports at least one head that is configured to interact with different tracks of the plurality of tracks on the at least one data storage medium to service commands from a host. The data storage device further includes a seek control circuit communicatively coupled to the at least one actuator. The seek control circuit is configured to store the commands from the host in at least one queue for execution by the at least one actuator. The seek control module is also configured to adjust power provided to the at least one actuator for seek operations to the different tracks of the plurality of tracks based on command age-related measurements of the commands from the host.

    Abstract: Method and apparatus for distributing wear in a disc stack. A data transducer is used to record data to a data recording surface in the disc stack. Performance statistics are accumulated including a dwell metric value indicative of dwell time of the transducer adjacent a selected radial location and an operational life metric value indicative of accumulated elapsed operation of the transducer. Data are migrated from the selected radial location to a target location within the disc stack responsive to at least a selected one of the dwell metric value or the operational life metric value. In some cases, the dwell metric value may indicate an estimated amount of lubricant disturbance and the operational life operation may indicate operational hours of a heat assisted magnetic recording (HAMR) element. The target location may be on a different data recording surface having an associated transducer with a lower operational life metric value.
