    Hello guys,

    I have a 512 GB Samsung 840 Evo + 750GB standard HDD in my Mid 2012 MacBook Pro 13''. I want to do a clean install of El Capitan.

    Until now I've been using my Home folder in the standard HDD and the OS on the SSD, but I wanted to give a try to a DIY Fusion Drive, as I'm starting over with the OS.

    Has anyone accomplished this? Given the fact I haven't found any info, I have these options:

    1.- Take the risk, make a clean install of El Capitan beta and try Fusion Drive directly, with the same instructions as Yosemite/Mavericks
    2.- Clean install of Yosemite, try Fusion Drive and make an update installation of El Capitan Beta
    3.- Clean install of Yosemite, try Fusion Drive and wait for the final release of El Capitan.

    Any opinion? What should I do?

    Thanks in advance!

    Havent tried, fusion drive on el capitan yet but tried it on mavericks and yosemite. Works ok. But i think it is better when you separate the os on the ssd and just the files on the hdd. It is much more efficient. Fusion drive is much slower than pure OS ssd.

    I've done something very similar: 2007 Core 2 Duo MBP with Samsung 840 Pro 256G, plus 500G Seagate installed in the optical bay. For a few years I manually managed files on two drives but recently did the DIY Fusion thing with a clean install of Yosemite, which I later followed with upgrade to the El Capitan beta. Haven't noticed a slowdown myself, and it's certainly more convenient.

    However, the process left me without a recovery partition---annoying, but no big deal since I carry a thumb drive with an installed OS.
