Some may remember when I first got my Late 2012 Mac Mini I added an SSD along side the standard 500gb Hard Drive and upgraded the Memory from 4gb to 16gb. Well now I have upgraded again! The Original SSD was a SATA II OCZ Vertex Plus 120gb but after finding out that OCZ SSDs were not known for their reliability I was waiting for SSDs to come down in price and finally snagged the Samsung 840 Evo 250gb SSD for £73 which I think is pretty good! I have moved the 500gb Hard Drive to the top bay and have the SSD in the bottom bay for easier access. I used SuperDuper to clone the old SSD to the new one which took about an hour. The boot time has now halved from around 10sec to around 5sec, and the newer SSD is also SATA III and has double the cache. Very pleased with the upgrade so recommend this to anyone running a Traditional Hard Drive or even a SATA II SSD. Tools and Parts Used: SuperDuper! for Hard Drive Cloning. OWC Data Doubler Kit to allow two drives to be installed. Samsung 840 Evo SSD on Amazon or if in UK use Flubit for cheaper price. USB 3.0 External Hard Drive Enclosure to put new drive in for cloning. OWC Youtube Video explaining exactly how to dismantle your Mac Mini. The great thing is my Mac Mini is now ready for Yosemite when it gets released which I am guessing is in October. Just thought I would share this incase anyone else is thinking of doing the same, if you have any questions or comments please let me know.
