The disclosure is related to file-aware caching for data storage devices. In one example, a device may comprise a data storage medium, an interface circuit to communicate with a host, and a driver configured to retrieve file system information related to a structured input/output (I/O) command from the host, and select caching attributes based on the file system information. Further, a system may include a host and at least one driver operating on the host; the driver configured to intercept a I/O request initiated at the host, obtain operating system information from the host about the I/O request, and store the operating system information that it is accessible to a data storage device to allow the data storage device to implement caching attributes based on the operating system information.

File-aware caching driver

The disclosure is related to systems, devices, and methods for file-aware priority drivers in data storage devices. In one example, a device may comprise a data storage medium, an interface circuit to communicate with a host, a driver configured to retrieve file system information related to a structured input/output (I/O) command from the host, select priority attributes based on the file system information, and prioritize execution of the I/O command based on the priority attributes. Another embodiment may be a method comprising inspecting characteristics of an I/O request, choosing priority attributes for the I/O request based on the characteristics, and executing operations in an order based on the priority attributes.

File-aware priority driver

Systems and methods are disclosed for intelligent data caching behavior. In an embodiment, a method may comprise receiving a read or write command for specific data, determining related data associated with the specific data, and directing the related data be stored to a cache. In another embodiment, a system may comprise a host device, and at least one driver operating on the host device. The at least one driver may be configured to intercept read or write command from the host device to a data storage device regarding specific data, obtain information from the host device to determine associated data related to the specific data, and direct the data storage device to store the associated data to a cache memory.

File associated pinning

Systems and methods are disclosed for intelligent data caching behavior. In an embodiment, a method may comprise receiving an indication a user has selected specific data for caching, and storing the specific data to a cache memory. In another embodiment, a system may comprise a host device including a driver configured to monitor the system for an indication a user has selected specific data for caching, and store the specific data to a cache memory. In yet another embodiment, an apparatus may a data storage device including a nonvolatile data storage medium, a cache memory, and a processor. The Processor may be configured to receive an indication a user has selected specific data for caching, and copy the specific data form the nonvolatile data storage medium to the cache memory.
