A method of operating a data storage device is provided. Size information of write data and write speed information is received from a host. A first write area is determined to store the write data based on the size information and the write speed information. The write data is received from the host. The write data is written to the first write area using at least one method selected among a plurality of write methods according to the write speed information.

Method of operating data storage device using size and write speed information and method of operating system including the same

An embedded multimedia card (eMMC) and a method of operating the same are provided. The eMMC includes a flash memory and a device controller configured to control the flash memory. The device controller includes a command storage unit configured to receive a command transmitted from a host regardless of a state of a data bus and to store task information by task ID; and a status storage unit configured to store status information based on task status by task ID.
