Windows software for Blackmagic's HyperDeck Studio.
HyperDeck Studio uses two SSDs for perpetual recording that lets you record forever! If you run out of space on one disk, it automatically switches to the second disk with no manual intervention required. The first drive can then be conveniently replaced while recording, ready to take over again when the second disk is full. You can “hot plug” disks at any time without fear of lost media.
