I have a late 2012 i7 Mac Mini, 16GB ram, 1TB internal hard drive and I added a 256GB SSD drive when I first bought it. Made the 256GB the boot drive, 1TB internal holds main storage (which now only has 341GB free). I am getting notifications that my 256GB SSD is out of room. I would prefer to not use an external HD as I have had issues with external devices in the past. I'm thinking I would like to replace the 256GB SSD with a 1TB SSD, but I do not know how I can get all of my data to the new drive. Do I just temp swap out the 1TB HD, put the SSD in its place, do some sort of a disk clone, then replace the 256SSD with the new drive and put the 1TB hard drive back in? Not sure the best way to get this resolved... Thanks in advance for any help!
