Device for real-time streaming to an array of solid state memory device sets, said device comprising receiving means for receiving data from data streams of individual data rate in parallel, an input cache for buffering received data, a bus system for transferring data from the input buffer to the solid state memory device sets, and a controller adapted for using a page-receiving-time t_r, a page-writing-time wrt_tm, the data amount p and the individual data rates for dynamically controlling the bus system such that data received from the first data stream is transferred to solid state memory device sets comprised in a first subset of said array of solid state memory device sets, only, and data received from the at least a second data stream is transferred to solid state memory device sets comprised in a different second subset of said array of solid state memory device sets, only.
