Dave Hamilton, writing at The Mac Observer:
In a nutshell, Fusion Drive combines TWO drives, a solid state drive (SSD) and a mechanical drive. Apple’s initial incarnation puts a 128GB SSD in with either a 1TB or a 3TB mechanical drive. This is not a simple RAID, however, as 100% of the “magic” is done within OS X itself. What Fusion Drive does is it watches what files and applications you run most regularly and it moves them to the SSD. It will also take stuff that you aren’t using all that often and moves it to the mechanical drive.
