The camcorder is equipped with two SxS memory card slots, which can record in Simul, Relay or Back up mode. Simul mode permits simultaneous recording to two memory cards, including simultaneous recordings of MPEG HD exFAT and UDF recordings, ideal for archival purposes. Relay mode automatically switches recording from the first to the second memory card when the first is full to extend recording times. In Back up mode, users can set up the two Start/Stop buttons on the PXW-Z280, one on the grip and one on the camcorder body, to independently start and stop recording on different memory cards while recording in Simul mode.*

*Simul and back-up recording are limited to HD operation
