Hi all, I'll try to keep this short. I just ordered a WD Mybook Studio for the Mac. I plan to use it to sync with Time Machine along with putting my all my videos, music, etc. on. I'm kind of an OCD person when it comes to my computer. I have a 500 GB Macbook Pro, and the HD filled with about 100GB of videos. Not videos that I watch all the time either.. I watch them periodically, but I am not always accessing them. I'm wondering if I should move said media to the external HD and get rid of it on my MB, or keep a copy on both.
