Step 8 – Get ID information for Fusion array. Once you enter in this command, it’ll do its thing and set-up the drives into an array for Fusion. In our example, they are “disk0” and “disk1”, but it may be different in your setup.

driveIDs – these are the drive IDs of the drives you want as part of your Fusion array, separated by a space.

You can call it whatever you want in our example, we named our Fusion array “Fusion.”

drivename – this is the name of the drive and how you want it to appear in Disk Utility (not the Finder – that comes later).

cs – this invokes Core Storage, which is necessary for Fusion.

diskutil – the command-line version of Disk Utility.

This is the command that actually tells your Mac to tie the drives together in a Fusion array. In Terminal, type: diskutil cs create drivename driveIDs In most cases (2 drives internally and booted from the external), the IDs will be “disk0” and “disk1.” However, individual results may vary, depending on your setup, so you’ll want to make sure you have the right drives. In the results, you will find the disk IDs of the HDD and SSD. This will have the command-line version of Disk Utility (diskutil) that lists all the disks attached to your computer. You can find it in Applications/Utilities/Terminal.app Step 6 – Find Your Disk IDs. That’s okay just click “Ignore.” We’ll be initializing it over the next couple of steps. If you installed at least one brand new drive, you will likely get a message about a disk being unreadable. Then, log in to the desktop like you normally would. We need to boot to the version of 10.8.2 that came with the Mac mini, but since you can’t erase the drive if you’re booted to it, simply boot to your clone by holding down the Option key at startup and selecting the external drive you cloned to (it’ll have the orange icon). See our video page for our step-by-step instructions on installing one or both drives into your mini.

Step 3 – Install the new drive(s) in the computer you’re upgrading. If you’re using the same drive that you already have installed, you will need to copy that drive’s contents to an external one. If you are installing both a new SSD and a new platter-based drive into, you can put your original drive in an external enclosure, and your data will be there, out of the way.

This process will erase both the installed SSD and hard drive, so if you have data on one or both of these drives, you’ll want to have a copy that’s not on either of the two drives that are going to be part of the Fusion array. Step 2 – Have a copy of your computer’s data. This is absolutely necessary, as the proper version of Disk Utility for doing this is on 10.8.2 or later on the mini and you want the OS versions to match. Make sure the OS on the mini’s drive is updated to 10.8.2 or later.

An external drive to clone to – creating a Fusion volume will erase both the SSD and the hard drive, so if you have information on the hard drive you want to keep, you’ll need to have a copy of that data elsewhere.

A hard drive and an SSD installed/to install internally – Fusion is designed to work on internal drives only.

A 2012 Mac mini – this is an absolute requirement as these are the only machines that currently have a version of Disk Utility that can create a Fusion volume.

First, though, let’s look at the process of actually setting it up. Of course, there are a few caveats to this setup (or the stock Fusion Drive, for that matter) that you should consider before committing to a Fusion setup. However, you don’t need to have a Fusion Drive from Apple to do this with the proper command-line version of Disk Utility, you can create your own array with any platter-based drive and any SSD. The practical upshot of all this is that Fusion gives you roughly the performance of an SSD, while also taking advantage of the plentiful storage of platter-based drives. Apple’s underlying Core Storage technology then uses the SSD for the OS and frequently-accessed files, which will benefit from the speed, while placing lesser-used files on the larger, but slower platter-based drive. This is essentially a Solid State drive and a platter-based drive combined into a single volume. One of the newest technologies available with the latest Macs is the ability to have what Apple calls a Fusion Drive.
