Simple (hopefully!) question: I have an iMac Intel 21.5" Retina 4K Display (2015) configured with a single 1TB HDD, which is starting to fail. While replacing it, I’m curious if I can add a blade SSD in addition to swapping over the HDD. Pretty sure there’s space there, just not sure about the connections.
Sadly, if it was not bought with a blade SSD it won’t have the connecter. Here’s the specs of your system: iMac 21.5" 3.3 GHz i7 (4K, Late 2015) the i5 3.1 GHz model is the same.
