If I replace the HDD with an SSD, I'd then have with 2 mountable drives, correct? Which would you recommend using as the boot drive? My instinct is to use the PCIe as the boot drive, and store most files on the SATA SSD, but not sure. using a Samsung, or the Crucial SSD that iFixIt sells?ģ) PCIe blade? From what I understand, the fusion drive is really comprised of a regular spinning SATA drive, and a 128GB PCIe flash drive, linked in the OS.

OWC's upgrade kit seems to come with their own "Mercury Extreme Pro" SSD-thoughts on this vs. I wonder if anybody can speak to the difference between them? I'm leaning towards iFixIt.Ģ) SSD model? What would you recommend? I've seen others mention a Samsung EVO to use for the HDD > SSD replacement. I've been reading the forums to get a sense of what this entails, but I have a few questions:ġ) Upgrade kit? I see that both iFixIt and OWC sell upgrade kits. I have a ~6 y/o 27" iMac (late-2014) that has a 1.12 TB fusion drive, which I'm looking to upgrade to a 1TB SSD.
