Can OS X be installed on the ssd part of the fusion drive? I am looking at purchasing a mac mini and need to decide on a storage option.
I want either an ssd or the fusion drive however I am not sure whether OS X can be installed on the SSD part of the fusion drive which is one of the main reasons that i want an SSD.
Yes, there's a way to install OS X on the SSD. It's called "install OS X on the Fusion Drive."

The Fusion Drive automatically puts the most frequently-used files on the SSD. When there are vital system files that your hard drive needs to access in its every waking moment, there's really no reason why the Fusion Drive would ever demote it to the HDD.
