You would get better performance if everything was running of an SSD on your mini, however, with that being said, Apple's SSDs are extremely fast. On a 2011 MacBook Pro with an SSD installed I get 220 MB/s read and 180 MB/s write, but with and SSD in the 2012 retina macbook pro, the same SSD that comes with the fusion drive, I gat 480 MB/s read and 420 MB/s write. Even though they are both SSDs, the Intel 830 can't meet Apple's SSD. There is also the problem of setting it up. If you get a Mac Mini with a Fusion drive, the whole thing will be set up to fun together and store files properly. If you choose to install your own SSD, you will still have to configure the fusion drive through the terminal and it still may not be compatible. If it were up to me, I would get it shipped with a fusion drive and avoid the possibility of incompatibilities and other issues you could encounter, but hey, that's my opinion, you can decide what you would like to do.
