Hi guys, I've decided that I want to get the new 13" MBP, but I am not sure how much storage I should go for. I had been expecting to go for the 1TB option, but now that I see it will cost me $600 more, I am wondering if I should just go for the 512gb and get acquainted with an external drive, even though I hate the idea of having something extra to have plugged in to work on things. I have a ton of pictures and they take up a lot of space, and I am wondering if it will only be a matter of time for me to outgrow the 1TB anyway. I know I can't be the only person who's dealt with this, so I was hoping someone might share how they've managed. Are you happy with how everything's worked out? Or would you just pony up the extra cash to avoid the headache of having the extra drive? I guess one of my biggest questions is whether or not the Photos app can work with two drives at the same time without having to close and reopen the app. I'd be happy if I can store the new photos locally and then move them over to an external drive when I'm done editing them, but I'm not sure if I can do that without having to create multiple libraries that can't be opened at the same time. I know this worked in the old version of iMovie that I have, but obviously Photos is a different program.
