I recently acquired a new 2.6 Ghz Mac mini with the following configuration: 16 Gb RAM 2 x 240 Gb Mercury Pro SSD drives internal 1x 320 Gb 7200 external Mercury Pro HD drive 1 x I Tb x 5400 external 1 x 2 Tb Mercury Elite Pro external. I want to separate the OS and applications on the internal SSD drives. How best to do that? At the moment I am only running and saving to the first SSD drive. The 320 Gb external must then be bootable copy of the OS and Applications folder. The 1 Tb will contain the back-up data. The 2Tb a Time Machine back. What programs are best used to accomplish this so that it operates seamlessly? Take care, Roy
