I want to apologize in advance to a lot of you that might see my question as pretty elementary, but it is something I don’t understand. I have a 2011 mbp with a 1gb of ssd storage and my iPhoto library is about 450gb. What do you do if you buy a new MacBook Pro that only has 256 or 512gb of flash storage? You would have to store that externally I guess? Would I put my entire iPhoto library on an external drive and then it is only accessible when I have that external drive with me?
