Adding an SSD drive to fusion 2014 Mac mini

My question was about placing the SSD alongside the Fusion as a start up drive. However the link you provided seems to indicate that the 2011 is very different than the 2014 and that there is no room for a second drive. I could be wrong and perhaps someone else can elaborate on this . My SSD is a 250 Crucial , about double the size of the Fusion SSD start up drive. Besides is still is not clear to me if the Fusion drive is one enclosure with both the SSD and the rotational drive or if they are separate occupying different bays. My Crucial is very fast .

I Am a bit confused my SSD is a 2.5 . What is a bladeSSD?

I see . is like a memory chip . Is that the Fusion drive that is under the thin chip board ?

Now if I understand correctly the ssd and the HD form a logical drive or a group equivalent to ONE drive . Why couldn't I install my other 2.5 SSD in the vacant bay?

Thanks a lot . If there is no vacant bay then the only way to incorporate the Crucial 250 SSD would be, like you initially said , break the logical group some how , remove the Blade SSD and then incorporate the Crucial SSD . I don't know if this will be feasible or if it will provide any advantage . I am migrating to the new Mini and will see how fast it will perform in its original configuration.

Thanks a lot for all your answers.

Thanks a lot . Now I have a clear understanding of my options and they are not really worth the trouble. If I remove the Rotating HD and install my Crucial in its place I will end up with just about 500 Gig of SSD instead of the original 2 Terabites . Of course the 2 Tb can go outside but the question will be whether the Crucial as a start up SSD would be faster than the original configuration. I will keep p all this in mind for when I have some benchmarks .

Thanks again. Luis

Thanks again.
