Abstract: A data storage device includes a first memory device configured to provide first read data in response to a first read command, a controller including a hardware filter configured to generate first hint information based on a result of comparison of the first read data with filtering condition data and a processor configured to determine whether the first read data is to be filtered based on the first hint information, selectively filter the first read data based on the filtering condition data based on the determination result, and generate first filtered data, and a second memory device configured to store the first filtered data. The controller communicates the first filtered data to a host.
