Data transfer management from host buffers

The present disclosure generally relates to efficient data transfer. Rather than processing each command, the data storage device fetches part of the host buffers and then makes a determination regarding the attributes of the fetched buffers. Upon the determination, the command is classified as optimized, not-optimized, or somewhere in between. Optimized commands are permitted to retrieve data out of order while non-optimized commands remain in a strict in order data retrieval process. In between commands can be processed with some out of order data retrieval. In so doing, data transfers are effectively managed and optimized data by taking into account the current attributes of the host buffers per command.
