Greetings community, I am very much an avid amateur/hobbyist looking for expert/experienced advice. I use FCPX and other programs to edit video taken from my DSLR (I soon will be experimenting with ML Raw on the 5D MKIII). I currently have a MacBook Pro 2011 (2.2ghz i7 with 4GB of ram) I would like to unload much of the video/music/data off my HD onto an external HD and use that HD for backup (Time Machine, which I have never used) So that is 1 HD for backup Also, I would like to purchase a fast HD to edit video, render it, then export it to a final file and transfer to the other HD for backup and clean up the files on it for a future edit. So to recap I need advice: 1. A HD for back/storage of all files (time machine) including video from FCPX and other programs as well as finished products (edited pictures/videos) 2. A HD for fast editing/rendering/editing/exporting of new projects What advice can you offer? I also may look to get a new iMac by January or a refurbished one as that may warrant better performance than my current configuration. Thoughts? Thanks!!!
