Hello! First I want to thank the many contributors to this wonderful site! I am hoping someone can help with an SSD installation I would like to do into my 2012 Mac Mini. 1. I have a 2012 Mac mini 2.6Ghz i7 Quad Core with 16GB ram and originally with a Fusion Drive. I recently removed the 1TB HDD from the mini using the guide on iFixIt.com. I then installed a Samsung 840 EVO 1TB SSD and booted in recovery mode. Disk utility sensed the missing 1TB HDD and offered to "repair" the 2 drives in the machine (the Apple 128GB SSD and the new Samsung 1TB SSD). That was completed and now I have 2 separate drives in Finder (they were not combined as a Fusion Drive). I installed the OS X on the new 1TB SSD and made it my boot drive. GREAT! So far so good! 2. I am thinking now that this is working well, down the road, I may want to get rid of the Apple 128GB SSD and replace it with another Samsung 840 EVO (currently $399 on Amazon) or 850 Pro (when the prices down a bit - it's currently $599 on Amazon). In fact, I'm kind of tempted to do it immediately. I am wondering if I can just remove the 128GB SSD and then just put in another Samsung 1TB SSD and have disk utility recognize this and "repair" it without losing data on my original Samsung 840 EVO 1TB SSD. The other concern I have is whether the 128GB SSD uses a different connector than the Samsung. I heard that Apple uses a "blade" connector but because there was a piece of black tape covering the Apple SSD I didn't want to tamper with it. In hindsight I should have checked it while I had the machine open. Thank you for any insight anyone can provide!
