    Hey there!

    Hoping you guys can help me, new to posting in the forum but have been an observer for many years :D

    I currently have a Macbook Pro9,2 - Mid 2012 13” 2.5GHz i5 8GB RAM. The default hard drive is slowing down in life, plus I have been doing more video editing with the video files taking up more space, so I decided to invest in an SSD and a HDD, with the plan of removing the optimal drive bay, and installing both.

    Currently: 500GB APPLE HDD HTS547550A9E384

    Upgrade: 250GB Samsung 850 EVO SSD
    1TB Hitachi HTS721010A9E630 Travelstar 7K1000

    In addition, I have an external enclosure (The idea being I will put the original 500gb drive in it) and an external drive bay enclosure for the MBP superdrive. Also I have tools for disassembly etc.

    Now I have found many many guides for installing straight from a hdd to an ssd but not so much for a split from hdd to a ssd and hdd. To make things even more complex I was hoping to do a clean install of the OS, choosing which files to take with me (I migrated the past TWO macs I had, so it is definitely time for a clean refresh I thought?).

    It may sound stupid but I don’t know the best way to do this. If people could give me there thoughts/plan of attack I would greatly appreciate it. Also, how people would split the what goes to the ssd and what to the hdd!

    You guys are awesome so I look forward to your response; I feel like I’m Apollo 13 and you guys are Ground Control creating me a CO2 filter out of my equipment!

    Many thanks and let me know if I'm missing any info out and I will update. Thanks again guys! :)

    You could use the guides to create your own DIY fusion drive. That way, OS X will automatically shift files between the HDD and the SSD based on your usage.

    Just install the SSD in the HDD bay, and use an optibay for the upgraded HDD.

    Internet recovery will allow you to download and re-install OSX.


    I'd just install OSX on the SSD and keep everything else on the HDD.

    When I did the same thing, I simply popped the SSD in, installed OS X onto, clean install.

    Once I was satisfied everything worked to my liking, I installed the hard drive in my opti-bay. Transferred all my files by hand to an external, formatted the hard drive 2 parition (1 for OS X storage, 1 for Windows storage) and put my files back in.

    As a secondary drive, Samsung (Seagate) have this SpinPoint 2TB drive that can fit in the optibay.

    I have the SSD in the Optibay but aside from that:

    I cloned the HDD to the SSD except the iTunes Media folder and my photo library (80GB and 250GB respectively at the time).

    Once cloned I booted from the SSD, then pointed iTunes and Aperture to their libraries on the HDD.

    Once happy everything was working normally, I deleted all files on the HDD except the iTunes Media folder and my photo library.

    Job done.
