Okay so i have a 2012 15" cMbp with the standard 500GB hdd and I am looking at getting a 3TB external hard drive for my iTunes library and all of my media. I have over 600Gb of music that I will be putting on the external along with all of my movies since I am in the process of Riping all of my DVDs and putting them in my library. !. I have about !00Gb of movie right now. is there a way to move all of that to the external drive easily? 2. Will I be able to have say just 10GB of music and some movies on my internal hard drive and then have the rest on the external and have some way to swap movies and music from on hard drive to the other? 3. When I import something to iTunes is there a way to choose what hard drive the content goes on? Thanks in advance.
