Abstract:
A storage system includes a host and a storage device. The storage device includes a device controller and a device interface. The device controller is configured to generate interface idle time information in response to a command received from a host, the interface idle time information being determined based on an estimated time to execute at least one operation at the memory storage device. The device interface is configured to output the interface idle time information to the host.
Abstract:
A storage device of a storage system includes a device Direct Memory Access (DMA) configured to calculate a data transfer amount based on size information of data provided to a DMA queue; a command manager configured to receive the data transfer amount from the device DMA and to calculate a transfer speed using a speed mode table; and a device interface configured to transfer the transfer speed to a host.
