Yesterday I replaced the hard drive for an SSD in my Mac Mini late 2014 (mine is the lowest range of the latest mac minis, with 4GB non-upgradable RAM), I had to take apart the whole machine, which wasn't easy at all. I measured the transfer speed with Blackmagic Disk Speed test and found the speed increase a meager 50MBps (from 98 MBps to 149 MBps). I was a little disappointed. I expected a much bigger increase. I hope I'm wrong somehow. Would the speed be much higher with a more powerful processor or more memory?
