I just recently heard about fusion driving a Mac to combine 2 internal drives to act as one from what I've read, my MacBook Pro from mid 2012 has a 512ssd in the main boot drive and a 750 gb Hdd in where the SuperDrive was.

Wondering if anyone has done fusion drive on a MacBook Pro from around when mine was made, how it went ( I.e how difficult it was ect) , if performance really increased at all, and if you ran into any other problems after doing this , and if you have/know a really good tutorial to do this.

Thanks

Vanessa

MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8)

    It is not yet possible to run bootcamp from a fusion drive because windows does not know how to read a fusion drive.

    How to create a Fusion Drive

     

    Info:

    1. Always first Backup all data on an external drive. Best usage CCC for a bootable system.

     

    2. Prepare for all steps to follow and be sure to understand the procedures fully.

              When you setup a Fusion Drive (conventional Hard Drive and SSD Fused together) both           drives will be erased and can only be used (both) to each 100% for such setup.

     

    ================================================================================ ====

     

    Setup:

     

    A. Startup from an external hard drive since, when you start to set the Fusion system up, NOTHING               can run on the drives you want to fuse.

     

              You also can (and I suggest to do so) reformat both drives first via "Disk Utility" to be sure to have a clean           system.

     

    B. Open "Terminal" (inside the Utilities Folder or via the top menu if you are using the Restore Disk           form one other Drive).

     

    C. At the insert point enter: diskutil coreStorage then hit "Enter" (also known as "return").

     

    D. The Terminal should respond with the following:

    E. Select the Drives you want to fuse, to do that enter into Terminal diskutil list followed by "Enter" (also known as "return"). The next window should look similar to the following:

     

    Screen Shot 2012-11-20 at 3.05.36 PM.png

     

    F. Take note of the first line (/dev/disk#) whereas the # indicates the number of which disk is which. This is important for the next step. Be sure you select the right ones.

     

    G. Now enter into the Terminal  diskutil coreStorage create myLogicalVolGroup /dev/disk# /dev/disk# whereas  # represents the number of the drive you want to select to be fused followed by "return".

     

    The following window shows after a short time:

     

    Screen Shot 2012-11-20 at 3.13.54 PM.png

     

    H. Take note of the identifier for the "discovered new Logical Volume Group" or the "Core Storage LVG UUID" both are the same ID.

     

    I. Now enter  diskutil coreStorage createVolume 50B457C3-ADC6-4EDC-9ABA-FD8C6EEDE69A jhfs+ "Macintosh HD" 100% whereas (50B457C3-ADC6-4EDC-9ABA-FD8C6EEDE69A) must be the number you wrote down from step H. When you now hit "return" the system will setup the fused drive.

     

    The next window should show:

     

    Screen Shot 2012-11-20 at 3.19.08 PM.png

     

    J. You are done. Now install the operating system, your Apps and your files back from your backup onto the newly created fusion drive and you will enjoy a speedy process.

     

    Short Setup Info:

     

    Enter into Terminal: diskutil list

     

    Note Disk ID /dev/disk# to be fused

     

    Enter into Terminal: diskutil coreStorage create myLogicalVolGroup /dev/disk0 /dev/disk1

     

    Note "Logical Volume Group"  ID (five mixed Numerical and  Letter Groups)

     

    Enter into Terminal: diskutil coreStorage createVolume (five mixed Numerical and  Letter Groups) jhfs+ "Macintosh HD" 100%

     

    Done

     

    Congratulations, Enjoy.

    Hi Vanessa i found this:

    Fusion Drive and Boot Camp

    Since Fusion Drive depends on software technology built into OS X, Windows doesn't support it. This doesn't mean Windows can't be installed on a Mac with a Fusion Drive, but Boot Camp Assistant will only create a partition on the hard drive.

    However, there is an issue with installing on a 3TB drive, whether that's a Fusion Drive or a garden-variety hard drive. Apple acknowledges that Boot Camp Assistant won't work with drives of this capacity. The maker of WinClone, an app which backs up Boot Camp partitions from within OS X,detailed the reason for this and how to overcome it.

     

    I hope it helps you,

    You can find the complete story on:

    http://www.techradar.com/news/computing-components/storage/fusion-drive-what-it- is-and-how-it-speeds-up-your-mac-1154051

     

    Your story helped me , because i became curious about what a fusion drive does exactly after reading your post, and then i think i found the answer to your question.

     

    I like how the fusion drive operates but by combining the two drives in my macbook pro i will lose the option of having an internal timecapsule, which i really like for some reason... (i also have an external one for double savety) I still have to think about it. Maybe its possible to first seperate the hdd into two partitions and then combine only one of them with the ssd to make a fusion drive... If the ssd ever fails i will still have timecapsule and after putting in a new ssd and emptying the fusion partition on the hdd i could make a new fusion drive and restore it from the time capsule.

     

    I not sure though it might be a lot of costly space to keep having an internal timemachine... maybe its just that i like the idea.

    Let me know if any of these thoughts helped you (or anyone else who reads this ofcourse)

     

    Good Luck

    What is the best configuration for 2 Drives, one SSD and a HDD? So which one is to put in the normal disk slot and which one in the adapter substituting the internal DVD device?

     

    Best regards,

    Giovanni

    Giovanni,

     

    Although there may be some optimization I'm not considering, I think it does not make any significant difference. Personally, I put the SSD in the hard drive slot and the HDD in the optical drive bay and that arrangement has worked fine for me.
