1. An operation method of a storage device including a nonvolatile memory and a memory controller configured to control the nonvolatile memory, the method comprising:
- receiving quality of service (QoS) information of a plurality of virtual channels;
storing the QoS information; and
accessing the nonvolatile memory using different schemes according to the stored QoS information and commands being received from the virtual channels, whereinthe plurality of virtual channels are channels through which the storage device communicates with an external device.

Abstract
An operation method of a storage device includes receiving quality of service (QoS) information of a plurality of virtual channels and storing the QoS information. A nonvolatile memory is accessed using different schemes according to the stored QoS information and commands received by virtual channels. The virtual channels are channels through which the storage device communicates with an external device.
