    Abstract: A data storage device includes a data store optimized organized into allocation units sized according to an sequential writing unit or garbage collection unit of the data store. Information is written to the allocation units as either coarse or fine-grained packets, which are packets of data that are self-describing and written together. Random writes received from a host to data already written into allocation units is written to another allocation unit, and a coarse-grained forward map is updated to reflect the physical location of the valid data that superseded data in the allocation unit until the allocation unit can be rewritten. Promotion operations are disclosed to compact data and garbage collect data by rewriting allocation units.

    Abstract: Apparatus and method for managing a media cache through the monitoring of operational vibration of a data storage device. In some embodiments, a non-volatile media cache of the data storage device is partitioned into at least first and second zones having different data recording characteristics. Input data are received for storage in a non-volatile main memory of the data storage device. An amount of operational vibration associated with the data storage device is measured. The input data are stored in a selected one of the first or second zones of the media cache prior to transfer to the main memory responsive to a comparison of the measured amount of operational vibration to a predetermined operational vibration threshold.
