I'm thinking of getting a new MBP for video editing, but the retina ones all have SSD's which is awesome because they are fast, but it's expensive to get a high capacity SSD, and they are not user replaceable, to my knowledge. Plus the RAM isn't user replaceable either. I dunno if I could live with 256gb internal memory, and I'm not willing to pay for the 512gb. Those of you who edit on the Retina MBP's, do you store your videos on an external drive? Do you just pull the content you need onto the hard drive when you are going to be doing the editing? Where do you store it all afterward? I have all my video content kept on various SD cards and external drives, but I prefer to keep a lot of it on my actual computer.
