Mac mini 2013 fusion drive diy
Was it slow even as standard SSD? What did you use to test rates? Did the drive s show reliable 6Gbit link rates? Intel is Sandforce based so writes are much lower with incompressible data. Not used it much otherwise so far though. It's an 8 core 2. I cloned my drive and followed their Terminal instructions which worked fine. After restoring all my data, my computer boots up and performs so much faster! Typical startup time from the startup chime until the login window appears used to be between 51 and 60 seconds.
With the Fusion drive it boots up between 16 to 17 seconds!
I just updated to Overall performance is improved from launching apps to compiling code. So far I'm very happy with this upgrade. Here are some caveats I've encountered along the way. I found I had lost my recovery partition even after reinstalling I found proper instructions with Carbon Copy Cloner which meant I had to reformat everything and start all over in order to keep a recovery partition available on the 1TB hard drive.
Gather your drives
That's all taken care of now and it works fine. The only other issue is Boot Camp 5. The window just sits there and won't go past the introduction screen. I can't repartition, even with the updated Disk Utility version 13 build So there doesn't seem to be a way for me to partition for Windows given that I have a Fusion Drive on an older unsupported configuration.
How to fix a split Fusion Drive
Oh well at least I still have Parallels working fine. That's all for now. Let me know if you have any questions. I'm sure you saw it already you noted bootcamp 5 but for anyone that missed it, the March 14th news page has Downloads of new Boot Camp 5. Had to reboot holding down Command - R and ran the Disk Utility repair. I started with my current system that had 4 hard drives in the system.
I had two gig drives in a raid as my boot drive - these were in drive bay 3 and 4. The problem with this is that OS X I'm running Fortunately I never needed it. I also had two 1TB drives in a raid for all my data. These were in drive bays 1 and 2. I had to go into disk utility after that and fix disk permissions before it showed up on the desktop. All I had to do after that was to re-download Mountain Lion from the App store, run it and install on the Fusion Drive.
During that process I had it migrate everything over from the raid array startup volume I originally had. Once that was complete, I pulled out the two gig drives from bay 3 and 4, replacing them with the two 1TB drives I had my data raid on, and I was back to normal. I wasn't actually sure that would work but it did!
Add your answer
I have not run speed tests but the system is noticeably faster and boots up much quicker. Thanks for keeping this site up. I have read it for a long time and check it a couple times a week. I used Disk Utility to format both drives, then followed the instructions to create a fusion drive on the OWC site. The createVolume stage subsequently passed off without problem, and the previous internal HDD GB Seagate Momentus, mounted in an external FW enclosure was used to restore the system.
Random restarts. Crashing halfway through installing OS X.
Disk Utility crashing. I rang Apple support and they talked me through splitting and re-makign the fusion drive but it was still unstable. It worked flawlessly installing Mac OSX up until the point where I rebooted, then it went into an endless repeating grey screen loop and never got to the desktop! Thanks, very useful post. No issues. The result turned out to be the the NVME drive speed and it seems to be very stable for the past couple hours with heavy load.
What enclosure is the 1TB eco in? Do you have a mac mini? Those machines require a special version of Mountain Lion that's not yet in the App Store. So in this circumstance, recovery mode is your best bet. List the drives you system can see. Use the following command to list the drives attached to your system:. Make a note of the mount points for the disks you want to make into a Fusion Drive. An easy way to tell drives apart is by their size and their name. Make sure you don't confuse them, as the Terminal doesn't give much warning before wiping your drive.
Create a logical volume group.
How to make your own Fusion Drive | Macworld
Let's create a CoreStorage logical volume group, the pool of data that will be made from the combined space of our physical drives. Use the following format of the diskutil command:. When the process is done, your logical volume group should be completed and the command will finish by presenting you with a unique identifier for the group, which you should copy to your clipboard. It should look similar to this:.
