I am looking at upgrading my mid 2010 macbook pro to the new 9.5mm 1.5TB 5k1500 hdd. Right now I have a large itunes library stored on external 1tb hd and some internal storage with OS on original 320GB hdd, but hate having to plug the external hd up to watch a movie through itunes. Anyone know of any issues with this drive or a better way to store and have a backup of my data? Right now the storage on the external doesn't have a backup and once I get everything moved over the 1 tb will be a backup of my internal hdd til it gets bigger than 1 tb. What is the best way to merge the external hd(itunes) with internal current os with the new 1.5tb internal hdd? I have heard about Carbon Copy for making a copy of my drives but don't want anything to screw up my storage. Any advice appreciated.
