The Mac II onwards were designed to use NuBus bus mastering for high speed data transfers. Both devices had to be on the NuBus, of course, and support bus mastering, at least as a slave. Possibly safer in a world of dodgy C programmers than DMA read/writes? Definitely more secure, as we have seen with modern FireWire implementations that allow the content of RAM to be dumped to an external disk.
