I have a 2.3 GHz quad core, 16 GB 1600 MHz RAM late 2012 Mac Mini. It ... is... dragging. It has a 1 TB SATA drive which I know is limiting it. I'm really looking into upgrading this Mac without putting a whole lot of money into this 6 year old machine. Boot ups are super slow. Loading Photos app takes minutes. I'd just love a refresh. I don't do Logic Pro or anything super taxing, so I am focusing on upgrading the drive. My questions are... 1) Should I go with fully upgrading to a 1 TB SSD? It seems like the best way, but it's expensive. 2) Use the data doubler and upgrade to a 500 GB while keeping my 1 TB available for storage. Can I load certain files and applications on the SSD to make it go faster while storing a large bulk of the data on the SATA drive? Or will that limit me? I'm just not certain how the two drives will behave together. Any suggestions? And do you also have suggestions for good SSDs? Read mixed reviews about the Crucials and Samsungs, but who knows.
