Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive a dataset management (DSM) hint, determine if a second physical memory range associated with a next read operation is located within a threshold number of physical block addresses (PBAs) to a first physical memory range associated with a current read operation, where the next read operation is provided by the DSM hint, and utilize at least a portion of a latency budget associated with the current read operation to optimize a read parameter of the first physical memory range.
