Zusammenfassung: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.
