A sustained status accelerating method for a storage device includes: controlling the storage device to receive a sustained status command from the outside; and controlling the storage device to enter the sustained status using a sustained valid page count (SVPC) table in response to the sustained status command so that each of a plurality of blocks constituting the storage device has a value greater than a predetermined valid page count. The SVPC table includes a valid page count with respect to each of the blocks in the storage device.

Storage device and sustained status accelerating method thereof

A data storing method of a nonvolatile storage device that includes a plurality of nonvolatile memory devices electrically connected to a plurality of channels is provided. The data storing method includes allocating part of write data provided from a host to the nonvolatile memory devices to each channel; determining whether at least one channel among the channels is present that is connected to a nonvolatile memory device in a last page offset state; and when the at least one channel is determined to be present, scheduling erase commands on the plurality of channels, scheduling write commands on the plurality of channels with respect to the allocated write data, and executing the erase commands and the write commands on the plurality of channels.
