The price of the Samsung 840 1TB SSD drive (on sale) finally made me buy one. After watching a bunch of Youtube videos, reading the ifixit guide and a bunch of forum posts I took the plunge on my 2012 Mac Mini (already upgraded to 16GB RAM when I first got it). My main fear in all this was breaking off one of those tiny connectors - something I did on a Dell laptop a couple years ago. Anyway - after cloning the internal boot drive to the SSD in an external FW adapter using CCC I was ready to go. The point of my post is to tell folks on the fence that it was relatively easy if you have the proper Torx and Hex drivers, a spudger, and a sturdy business card - along with some patience. After the disk cloning, the physical replacement took less than 30 minutes. I won't go through the entire process since you can see it at a bunch of places, but wanted to let folks know that: 1) No need to remove the case screw that is on the opposite side of the logic board from the hard drive bay. 2) No need to slide out the logic board at all 3) No need to remove the RAM modules 4) No need to unplug the fan - just unscrew and tip it out of the way 5) No need to unplug the WiFi antenna grate - also, just unscrew and tip it out of the way 6) The only connector I had to remove was the HDD SATA connector (using the spudger) Once the SATA cable is unplugged, the existing HDD can be carefully maneuvered out and the new SSD in (with help from the business card)with everything else still plugged into the logic board. Plug in the SATA cable, replace the grate, fan, cowl, screws and case bottom and the machine now boots up quickly and flies through tasks. It's amazing how fast it feels now compared to the old 1TB spinning drive.
