I am thinking about replacing the platter 1 TB HDD (part of the fusion setup) on my 2014 5k iMac to a 2TB SSD. This way I hope to have a 128GB blade SSD and a 2TB SATA SSD. Admittedly I haven't tried this since I replaced the HDD on my 2012 iMac to an SSD. Is everything the same? I read through some of the discussions in another thread but they didn't talk about the 5K iMac. Any tips or pointers?
