Probably a stupid question but figured I'd ask if anybody has any real world experience with this. I really like the idea of uploading my DVD collection onto the computer so it can stream to the ATV's throughout the home. The only problem is the HD in my new iMac is only so large (1TB). I thought about getting a really big external drive (i.e., 4TB or larger) and just moving my entire iTunes library folder there (music and movies). Any issues, performance or otherwise? Also open to any other options for the best way to store and steam a large collection. TIA for any replies!
