Hey guys, I currently am running a Mac Pro 4,1>5,1 with the dual quad core Xeons @ 2.26 ghz. I am running 3 plain 7200 RPM drives (One for Mac OS X, one for backups, and other for bootcamp) and i was looking to upgrade my Mac OS X one. I would like a SSD, but I have an excess of data that means going for a 1 tb+ drive, so the SSD for me is not very cost-efficient or in my budget. I was looking at an SSHD, but the only ones I see are the Barracuda's which seem decent, but I don't want to spend $100~ for a drive that only has 8gb of flash memory. After hearing all about the fusion drives and how the 2tb models have 128gb of flash memory, I am interested. Does anyone know where I can acquire one, if possible, for a decent price? Or if not, are there any better SSHD drives out there that give me more than 8gb of flash memory? That doesn't seem very good for the price. Thanks in advance!

Stick a 128/250/512 Gib SSD into the second optical drive bay. Use that as the startup drive only. Keep your junk on the other drives. I had a 2009 2.26 8 core MP. That's how I had it set up. Worked really great.

Thanks for the reply. Is there something I have to configure to make it boot off of that drive? Obviously installing OS X. But should I uninstall OS X from the platter drive and just leave the files on there?

Since a Fusion Drive is simply an SSD and an HDD in a special sort of software RAID, there's no "acquiring one". Just got any SSD and any HDD, and you can fuse them together yourself with a few Terminal commands

Will this make it work the same as one swell in the sense that it'll put all of my most used items on the SSD and the rest of the HDD? If so, do you have a link to the instructions?

It will work exactly like an Apple Fusion Drive. In fact, these are OEM Terminal commands provided by Apple.

For a guide, the following is really extensive:

Report back to me if you encounter issues and I can help :)

YMMV with regard to Fusion Drive. I found that once crossing the SSD barrier (especially if you are encoding files) that crossing that boundary could result in stutter as the encoding started in one write speed and degraded as it started writing to the hard drive. While there is convenience in one volume that Fusion Drive provides, unless you have a VERY small SSD (less than 128GB) I think you are better served with two separate volumes, even with the potential overhead that entails.

I've had two custom Fusion drive setups that worked ok for a number of months with satisfactory performance, but both configs eventually failed due to some sort of corruption I could not recover.
I eventually went to running boot from the SSD with key components located on the SSD and other things linked via symbolic links. I am now using a 2TB SSD as my main drive. The system has been utterly stable 24/7.
For media work, I place certain caches and work projects on the SSD, but keep the bulk on spinning platters.
