I have a 1TB pure-flash/SSD (not fusion drive) Late 2014 Retina 5k iMac. I believe that the SSD in this iMac is a PCIe x2 card, not a SATA drive, it’s whatever Apple put there in the factory. I would like to add an additional 2TB Samsung 850 EVO SATA SSD. Does this iMac, ordered from apple without a SATA drive, have a place for a SATA drive with the appropriate cables? If not, can I order the necessary parts? If there is space for a SATA drive, I believe that it fits a 3.5" drive, and that I will need a 2.5" to 3.5" adapter. Is this correct? Thanks!
Here’s how to add a standard drive, an adapter would work: iMac Intel 27" Retina 5K Display Hard Drive Replacement
