What kind of external HD's are you guys using? I have a 500GB external OWC right now hooked up via firewire 800. Now given, my actual dvd collection is about 500 and I have just starting ripping them. I figured by the end of it all I will have well over 1TB. Yes, I know I have a too many actual dvd's. But my question is for the guys that have over 2TB's. I was thinking of a OWC 2TB external HD. But didn't know eventually if I went over that amount how I would sync my iTunes library to two different external HD's?
