Okay I took a plunge and got 500GB Samsung 840SSD for my 2012 mini. Following are things I've done so far and just want to get input from others before proceeding further 1) Format SSD by connecting it to mini using USB-Sata dock. Created partition on it Mac-OS Extended journeled with option of partition as GUID partition table this way making it as bootable disc for OSX 2) Used carbon copy cloner and copied primary partition i.e. Macintosh-HD from my internal HDD to SSD. 3) Restarted mini and used startup manager using "Alt/Option" key on keyboard as I started mini. My confusion starts now, Booted from SSD as external drive and it took same amount of time it used to take when I was booting from my HDD. Is this normal or am i doning something wrong ? I just want to make sure before I put SSD inside mini and would have to open it again for soem reason.
