A storage system includes a host including a host queue storing a plurality of commands and a storage device including a storage queue exchanging commands with the host through a first port or a second port, and storing the exchanged commands, wherein the storage device is configured to, when a communication error has occurred through the first port, transfer information about a command stored in the storage queue before the error occurrence to the host through the second port.

Storage system and storage queue processing following port error

A storage device providing a function of securely discarding data and an operating method of the storage device are provided. The storage device includes a safety pin device removably mounted on the storage device, the safety pin device configured to store first encrypted information and second encrypted information, the first encrypted information encrypted using a first key associated with a first user, and the second encrypted information encrypted using a second key associated with a second user, security circuitry configured to, receive the first encrypted information from the safety pin device, decrypt the first encrypted information, and generate a data encryption key based on results of the decrypting the first encrypted information, and a nonvolatile memory configured to store data encrypted with the data encryption key.

Storage device providing function of securely discarding data and operating method thereof

An operating method of a storage device including a plurality of memory chips and a connection including a network command queue and a virtual command queue includes receiving a plurality of commands from a host device using the connection, selecting a physical command queue allocated to the connection among a plurality of physical command queues corresponding to the plurality of memory chips, sequentially storing the plurality of commands in the network command queue and the virtual command queue, and transmitting a command throttling request to the host device in response to the plurality of commands based on a queue depth of the network command queue and adjusting a number of physical command queues allocated to the connection based on a queue depth of the virtual command queue.
