    摘要： A new segment of data is copied to a volatile, primary cache based on a host data read access request. The primary cache mirrors a first portion of a non-volatile main storage criterion is determined for movement of data from the primary cache to a non-volatile, secondary cache that mirrors a second portion of the main storage. The criterion gives higher priority to segments having addresses not yet selected for reading by the host. In response to the new segment of data being copied to the primary cache, a selected segment of data is copied from the primary cache to the secondary cache in response to the selected segment satisfying the criterion.

    摘要： Host read operations affecting a first logical block address of a data storage device are tracked. The data storage device includes a main storage and a non-volatile cache that mirrors a portion of data of the main storage. One or more criteria associated with the host read operations are determined. The criteria are indicative of future read requests of second logical block address associated with the first logical block address. Data of the at least the second logical block address is copied from the main storage to the non-volatile cache if the criteria meets a threshold.

    摘要： A host read request affects a request address range of a main storage. A speculative address range proximate to the request address range is defined. Speculative data stored in the speculative address range is not requested via the host read request. A criterion is determined that is indicative of future read requests of associated with the speculative data. The speculative data is copied from the main storage to at least one of a non-volatile cache and a volatile cache together with data of the host read request in response to the criterion meeting a threshold. The non-volatile cache and the volatile cache mirror respective portions of the main storage.

    摘要： 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.
