The Fusion Drive was announced as part of an Apple event held on October 23, 2012, with the first supporting products being two desktops: the iMac and Mac Mini with OS. Make Offer - Apple Mac Mini 2014/8Gb/2.8Ghz/Intel i5/1TB Fusion hard drive/keyboard/trackpad. MAC MINI i5@2.5 8GB DDR3 1600 RAM 60GB/500GB FUSION DRIVE + POWER CORD $550.00. When you purchase a Mac with an optional Fusion Drive (currently, a Fusion Drive is a $250 upgrade to the $799 Mac mini), the OS and all of the applications that ship with a new Mac are loaded onto.

Fusion Drive, a storage option on some iMac and Mac mini computers, combines a hard drive and flash storage in a single volume for improved performance and storage capacity. If your Fusion Drive appears as two drives instead of one in the Finder, it's no longer working as a Fusion Drive. This can happen after replacing either drive of your Fusion Drive, or using software to intentionally split them into separate volumes.

You can continue using the two drives independently, or follow these steps to regain the benefits of having the single logical volume of a Fusion Drive.

Before you begin

If you're not sure that your Mac was configured with a Fusion Drive, or that the drive has been split:

  1. Disconnect any external storage devices from your Mac.
  2. Choose Apple menu  > About This Mac, then click Storage.
    • If you see a drive labeled Fusion Drive, your Fusion Drive is working and this article doesn't apply to you.
    • If you have a Fusion Drive that has been split, you should see two drives. One of them should be labeled Flash Storage, with a capacity of 24GB, 32GB, or 128GB. The other should be at least 1TB.

Use Terminal to create a Fusion Drive again

These steps permanently delete all data stored on the drives that make up your Fusion Drive. Make sure that you have a backup before continuing.

If you're using macOS Mojave or later

  1. Turn on your Mac, then immediately press and hold Command-R to start up from macOS Recovery. Release the keys when you see the Apple logo or spinning globe.
  2. When you see the macOS Utilities window, choose Utilities > Terminal from the menu bar.
  3. Type diskutil resetFusion in the Terminal window, then press Return.
  4. Type Yes (with a capital Y) when prompted, then press Return.
  5. When Terminal indicates that the operation was successful, quit Terminal to return to the macOS Utilities window.
  6. Choose Reinstall macOS, then follow the onscreen instructions to reinstall the Mac operating system. Your Mac restarts from your Fusion Drive when done.

If you're using macOS High Sierra or earlier

2014
  1. Turn on your Mac, then immediately press and hold Command-R to start up from macOS Recovery. Release the keys you see the Apple logo or spinning globe.
  2. When you see the macOS Utilities window, choose Utilities > Terminal from the menu bar.
  3. Type diskutil list in the Terminal window, then press Return.
  4. Terminal displays a table of data about your drives. In the IDENTIFIER column, find the identifier for each of the two internal, physical drives that make up your Fusion Drive. Usually the identifiers are disk0 and disk1. One of them should be 128GB or less in size. The other at least 1TB in size.
  5. Type the following command, replacing identifier1 and identifier2 with the identifiers you found in the previous step. Then press Return.

    Example: diskutil cs create Macintosh HD disk0 disk1

  6. If you get a disk unmounting error, enter diskutil unmountDisk identifier, using the first identifier you gathered previously. Then enter same command again using the second identifier. Then retry the command in step 5.
  7. Type diskutil cs list, then press Return.
  8. Terminal displays additional data about your drives (volumes). Find the string of numbers that appears after ”Logical Volume Group” for the volume named Macintosh HD. It's a number like 8354AFC3-BF97-4589-A407-25453FD2815A.
    Example:
    +-- Logical Volume Group 8354AFC3-BF97-4589-A407-25453FD2815A
    |
    | Name: Macintosh HD
  9. Type the following command, replacing logicalvolumegroup with the number you found in the previous step. Then press Return.

    Example: diskutil cs createVolume 8354AFC3-BF97-4589-A407-25453FD2815A jhfs+ Macintosh HD 100%

  10. When Terminal indicates that the operation was successful, quit Terminal to return to the macOS Utilities window.
  11. Choose Reinstall macOS, then follow the onscreen instructions to reinstall the Mac operating system. Your Mac restarts from your Fusion Drive when done.

With Apple now supplying Fusion Drives in their current generation Mac Minis & iMacs we thought it was about time we let classic Mac Pro users know how to get in on the action. A Fusion Drive is basically a software based SSHD (hybrid drive), it uses software to combine a regular, slower but higher capacity, HDD and a modern, faster but smaller capacity, SSD or flash storage module into one drive. OS X will then control which drive your files end up being stored on, all files will be stored on the SSD until it’s full, after this point your system will store only your most used files on the SSD.
In theory, this set up should manually optimise the way your files are stored, meaning the best possible storage performance without lifting a finger. Now, one may ask, surely a hardware based SSHD is superior to the software based Fusion Drive? Well, the general consensus is that Apple’s proprietary Fusion Drive software is in fact a superior file management system to those used in SSHDs.
With all this in mind, lets talk about how a Fusion Drive can help system performance. Any file stored on an SSD will see performance benefits over those stored on a HDD, quicker loading to RAM/CPU, faster application load speeds, faster OS X boot times, the list could go on. Basically, if something is important to your workflow, be that your OS, favourite applications, often used plugins or sample libraries, then they are best off stored on an SSD. Of course, this requires manual organisation, Fusion Drives attempt to alleviate this by analysing exactly what it is you use most often and then storing that on the SSD for you. The crux of the argument for a Fusion Drive? Pain free optimal storage performance.
So, what do you need to create a Fusion Drive?:

  • 1 or more HDDs.
  • 1 or more SSDs or flash storage modules.
  • The instructions below.

How to create a Fusion Drive in OS X:


Ok, lets get into this proper. Here’s the step by step guide to create your Fusion Drive. Of course you will need a HDD & SSD installed in your system before starting the process.

  1. Make sure that both your SSD & HDD are installed in your Mac Pro using the SATA or PCI-e bays.
  2. This process will destroy any data currently stored on your SSD & HDD, so please ensure they are backed up properly if there is data on them that you do not wish to lose.
  3. Boot into OS X (if you would like to use your new fusion drive as the boot drive then you will need to boot using an OS X USB Recovery Partition, if you need to create one follow this guide).
  4. Once you are booted into either OS X or your OS X USB, open Terminal. You can find it at the following path: ApplicationsUtilitiesTerminal.app.
  5. Inside terminal enter the following command: diskutil list
  6. All of the drives in your system will now be listed, each will reveal in mount point in the following format: /dev/disk#
    • The ‘#’ will be a number which is assigned to each drive by OS X. Make a note of the mount points for both the HDD & SSD that you wish to create the Fusion Drive with, you’ll need them shortly.
  7. We will now create the logical volume group using Core Storage, this will perform as a container for the drives that are being fused. You will need the mount points that you noted down in the previous step. Enter the following command into terminal: diskutil coreStorage create LOGICAL_VOL_GROUP_NAME DRIVE_1 DRIVE_2
    • In place of ‘LOGICAL_VOL_GROUP_NAME’ select a name for your new Fusion Drive.
    • In place of ‘DRIVE_1’ & ‘DRIVE_2’ use the mount points we jotted down before in the ‘/dev/disk#’ format.
    • So if you decide to call your Fusion Drive ‘Fusion Drive’ & your disk mount points are ‘/dev/disk1’ & ‘/dev/disk2’ then the command would look like this: diskutil coreStorage create ‘Fusion Drive’ /dev/disk1 /dev/disk2
      • Make sure you include the apostrophes around the name, otherwise the command wont work
  8. We will now create the logical volume, this is where your data will be stored. To complete this step we will require your LVG UUID, this is an identifier assigned to storage groups by OS X. After completing the previous step, Terminal should now display your LVG UUID as ‘Core Storage LVG UUID’. Make a note of the ID and enter the following command: diskutil coreStorage createVolume lvgUUID type name size
    • ‘type’ refers to the format of the drive, for OS X Extended use ‘jhfs+’. Don’t use a different type unless you know exactly what you’re doing.
    • ‘name’ refers to the name of the Fusion Drive that you set in step 7.
    • ‘size’ refers to the size of the Fusion Drive, use ‘100%’ unless you know exactly what you’re doing
    • If your lvgUUID is ‘12345678-1234-1234-1234-123456789123’, type is ‘jhfs+’, name is ‘Fusion Drive’ and size is ‘100%’, then you would enter: diskutil coreStorage createVolume 12345678-1234-1234-1234-123456789123 jhfs+ ‘Fusion Drive’ 100%
      • Again, don’t forget the apostrophes around the Fusion Drive name
