Apple's Fusion drives are a new thing. I haven't used a system so equipped as yet.
The idea is that you have both an SSD and a spinning drive which OS X treats as a single file system volume. As you work, the system figures out what sorts of things are opened and closed often, and how they influence overall system performance and app performance, and moves the things that matter to the SSD for you, leaving the rest on the spinning drive. These will be mostly binary executables, OS components, caches, etc ... things that are often created and deleted. The technology was too new for my comfort when I bought my Mac mini, I was not ready to experiment. I haven't heard much in way of serious issues with the Fusion drives, however. What I read mirrors my trepidation with any new technology. That's about as far as I can say.
