An implementation of a system disclosed herein provides a method for managing data streams of sequential nature, wherein the method writes the sequential chunks (fragments) directly to an open band in the order these are received from the host and includes determining an end of the incoming data write request related to streaming data and in response to the determination of the end of the incoming data write request related to streaming data, copying remaining data from a current physical band mapped to logical block addresses LBAs related to the data write requests to the allocated (open) band.
