Abstract: Systems and methods for recording and playback of multiple data streams. One device includes a storage controller coupled to an electronic storage device, a first data buffer storing data received from a first data stream, a second data buffer storing data received from a second data stream, a fragment buffer storing fragment metadata, a storage buffer including a plurality of data fragments, and an electronic processor. The electronic processor receives information designating a data stream storage area of the electronic storage device. The electronic processor arbitrates between the first and second data buffers to select a data fragment for writing to the storage buffer. The electronic processor writes the data fragment to the storage buffer, and writes fragment metadata defining the data fragment to the fragment buffer. The electronic processor controls the storage controller to sequentially write from the plurality of data fragments to the data stream storage area.
