Fusion Confusion
1

There's quite a lot of confusion around Apple's new Fusion Drive, and Arstechnica have posted an article recently which helps clarify what it is and how it works. To quote from the conclusion:

"The actual impact of the tiering [by Fusion Drive] on user operations appears negligible—actually using the Mini as a regular computer feels nice and quick, as if it were a regular SSD-equipped Mac. In fact, for a casual user with less than about 110 GB of stuff, FD shouldn't ever actually touch the hard drive. In our tests, it didn't begin moving anything anywhere until the SSD was nearing capacity, so users without tons of stuff shouldn't ever even know it's there. In that case, the advantage of Fusion Drive over a pure SSD is that if they eventually outgrow the SSD, the system will automatically grow with them, keeping less often-used things on HDD."
