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: An apparatus includes a data storage medium having a plurality of tracks. The apparatus also includes a write history buffer configured to store a history of prior write commands to the plurality of tracks. The apparatus further includes a controller communicatively coupled to the write history buffer. The controller is configured to receive a new write command directed to a first portion of a first track of the plurality of tracks on the data storage medium. The controller is further configured to determine whether to update ATI contribution measures from the first track based on the history of write commands to the first track.

Abstract: A data storage device includes a storage tier and a storage controller operably coupled to the storage tier and configured to be communicatively coupled to a host device. The storage controller includes a first memory operably coupled to the storage controller and configured to store a superseding data structure. The storage controller further includes a second memory operably coupled to the storage controller and configured to store a forward map configured to map a plurality of logical block addresses to physical locations on the storage tier. The storage controller further includes a sifting module configured to sift the forward map based on data contained in the superseding data structure. The storage controller further includes a compression module configured to compress the forward map to generate a compressed forward map.

Abstract: A hybrid data storage device disclosed herein includes a main data store, one or more data storage caches, and a data storage cache management sub-system. The hybrid data storage device is configured to limit write operations on the one or more data storage caches to less than an endurance value for the data storage cache. In one implementation, the data storage cache management sub-system limits or denies requests for promotion of data from the main data store to the one or more data storage caches. In another implementation, the data storage cache management sub-system limits garbage collection operations on the data storage cache.

Abstract: The disclosure is related to systems and methods of managing data storage in a memory device. In a particular embodiment, a method is disclosed that includes receiving, in a data storage device, at least one data packet that has a size that is different from an allocated storage capacity of at least one physical destination location on a data storage medium in the data storage device for the at least one data packet. The method also includes storing the at least one received data packet in a non-volatile cache memory prior to transferring the at least one received data packet to the at least one physical destination location.

Abstract: A data storage system includes data storage and random access memory. A sorting module is communicatively coupled to the random access memory and is configured to sort data blocks of incoming write data received in the random access memory. A storage controller is communicatively coupled to the random access memory and the data storage and is configured to write the sorted data blocks as individually-sorted data block sets to a staging area of the data storage. A method and processor-implemented process provide for sorting data blocks of incoming write data received in a random access memory of data storage and writing the sorted data blocks as individually-sorted data block sets to a staging area of the data storage.
