Adding an internal SATA HDD and SDD to a late-2014 27" 5K Retina iMac
I have the late-2014 version that came with a 1T SSD installed. I've been using an external Thunderbolt 2 RAID (OWC ThunderBay 4) to manage over 20T of photos and movies. Mostly I use Photoshop and Final Cut Pro.
My two questions are: 1) can I add a SATA SSD or HDD in the spot where an HDD would have been if I'd ordered it that way in the first place? 2) Would there be any speed advantage over my current set up? I was thinking about changing the original SSD to the OWC Aura 2 2T SSD and adding either a 4T Mercury Extreme Pro SATA SSD or a 4T 6G/s HDD to have internal access to projects I'm currently working on.
I've upgraded the innards of many iMacs over the years so I feel relatively comfortable with the project, but I don't want to open up the machine to find out there's no SATA connector in there, or that it wouldn't be compatible with what I'm proposing.
Thanks
