This is what I have now: 24" iMac, 300gb, 150 free 15" MacbookPro, 300 gb, 215 Free Apple TV, 40 gb, with nothing on it. Time Capsule w/500gb WD Mybook 500gb, 317 Free running superduper off Imac Just got me a Lacie 2T and want to do this: Store all of my Itunes (music and DVD's I've starting ripping) on it and be able to access from Laptop and ATV. Back-up all of the files on the Imac and Laptop. Should I just plug it into the imac via fw800 and format it as one large drive? What if I get another and want to use their RAID What about the Mybook? Daisy chain to Lacie and keep superduper? Or connect to TC? I'm pretty anal about backing up after losing all of my data after the Gustav last summer. Thanks for your help.
