Zusammenfassung:A storage system includes a host device supporting multiple queues and a storage device communicating with the host device. The host device may include first and second cores, first and second queues corresponding to the first and second cores and storing commands, and a host controller that sets a queue ID and/or a parallelism demand level for each commands stored in the first and second queues. The storage device may include nonvolatile memories and a storage controller that detects pattern information of commands, received from the host device, based on the queue ID and places the commands, received from the host device, in the nonvolatile memories based on the pattern information.
