    I'm just wondering what is faster & how much faster. Creating a Fusion drive with an external SSD & the Internal HDD or just booting from the external SSD? And if one is faster by how much?

    Rewritten (should have read OP's post more clearly):

    If you're going to use an SSD for an external booter, probably best to run it as a "straight SSD" without using fusion.

    I've been doing it for three years now, works flawlessly.

    If you don't have the Mini yet, best to get the 2014 model -with- the fusion drive already installed.
    The "blade" SSD used is MUCH faster than any SATA SSD.

    In theory the speed would be the same. The Fusion works by using the most used blocks of data to the SSD, and the OS would be part of that "most used" data, so it would be in the SSD.

    I would be very cautious about this setup though. If you some reason that external SSD gets disconnected while the system is on, you will have borked the Fusion drive and likely will lose any data on it.
