Mac mini (late 2012) Yosemite 10.10.5 2.3 Ghz Intel Core i7 16 GB 1600 MHz DDR3 I have a full backup on a portable SSD. I have a new 1TB HDD (thank you Apple Care). I'm going to add a 1TB Samsung 250 Pro SSD that will be installed by a couple of Japanese certified Apple Repair Technicians. My Japanese is not that good in this area. I'm thinking, since I have so much space on the SSD, I'd like to have the SSD "fully loaded" with the whole enchilada (system, document, applications-everything) as the main boot up drive disk and make the HDD a bootable backup (using ChronoSync) My Questions: 1. Is this doable? 2. Will having the SSD being a 'full bootable' slow the dive down significantly? 3. If YES for '2', what is a better 'speed performance' option? 4. In the event that it would be better to run 'System & Applications' off the SSD and use the HDD for my files, ie, User Folder, how do I go about making a backup of all this that will be bootable? Appreciate any suggestions. Thank you.
