A method begins by receiving streaming data. The method continues by partitioning the streaming data into a first data stream and a second data stream. For the first data stream, the method continues by encoding, in accordance with error coding dispersed storage function parameters, the first data stream into a first encoded data slices. The method continues by determining first memory of a DSN to store the first encoded data slices and facilitating storage of the first encoded data slices in the first memory. For the second data stream, the method continues by encoding, in accordance with the error coding dispersed storage function parameters, the second data stream into a second encoded data slices. The method continues by determining second memory of the DSN to store the second encoded data slices and facilitating storage of the second encoded data slices in the second memory.
