I got the new Mac mini with the Fusion drive option thinking I could live freely and let OS X manage where my stuff was. Turns out I was a bit too OCD for that. I found another thread that referenced this article:
http://arstechnica.com/apple/2012/1...ining-doc-ars-tears-open-apples-fusion-drive/
Here's what I did:
- Booted into recovery mode
- At a terminal prompt did a "diskutil cs list" to show the info on the Fusion logical drive
- Ran a "diskutil cs deleteVolume <guid of Fusion volume>
- Ran a "diskutil cs delete <guid of Fusion volume group>
- That broke the Fusion and I was able to run the OS X installer and install the OS to the SSD. Note, that going into the gui diskutil results in a prompt to "fix" your drives. When I did that, it re-fused everything.
- After OS X was installed, I created sym links for folders I wanted on the 1 TB 5400 drive. I used the commands in this article:
http://gigaom.com/2011/04/27/how-to-create-and-use-symlinks-on-a-mac/
Now I have full control over what goes where. Totally defeating the point of the Fusion drive. But now I don't have the "What the heck is the hard drive churning on when I'm not doing anything feeling?"
I'm still restoring all of my data, but so far, things appear to be working just fine. Just figured I'd share my experience if anyone else wanted to do the same.
