I'm going to be getting a new MacBook Air with 128GB of storage. My iTunes library is currentley about 400GB of TV programmes and films and all stored on my laptop that is about to give in. I dont want to depend on iCloud and all that so I will be keeping all my TV programmes and films that I have bought on my own storage. My question is, how can I manage my library with the use of external drives. Ideally I would like the following: All my music bought and downloaded from iTunes saving/saved onto the MacBook Air so that it is avaliable anywhere the MacBook Air is. All of the films / TV programmes that I buy and have bought being saved onto a NAS. All of which must be in the iTunes library of the MacBook Air so that Apple TVs can see it via home sharing and be accesed when at home. The only way I can see to do it is to have the library on the MacBook Air and when I buy anything manually move it onto the external. Is there a better way that im overlooking? I ask here as others must be in the same situation as me with MacBook Airs and have good solutions for managing it. Thanks for any suggestions in advance.
