I bought a 2014 Mac Mini with spinning hard drive a couple years ago... dog slow. painfully slow. unusable. I have been running it mostly from an external USB3 SSD boot drive which is pretty fast, much better than the hard drive was. Question: Would it be possible/efficient to run it from an SD card - SDXC (Secure Digital Extended Capacity) drive? The specs say it will accept 32 gb and larger cards in that slot. Anyone have an idea if that is worth doing? A 128 gb SDXC card is about $67 from Amazon. Thanks!
