Hi all, last summer I received my first mac, a 13" MBA. I do a lot of photo editing, music (recording, arranging, ext), light video editing, school stuff (word processing, evernote, ext) and then the everyday stuff. This said, I went with an i7 8GB RAM and 128GB ssd. I have a 500gb external drive, and have backups, and other files on it. It becomes bothersome because I need those files on the external drive at school, while the drive is at home. I was wondering whether I should just disregard the issue and move on with minimal space, which really bothers me, or if I should get a 128gb sd card to put in the slot? Please help me out with any way possible to fix this issue. P.S. I read somewhere you can change the disk space on the MBA, but Apple says it's not possible... Can I upgrade up to a 256GB or is that not possible? Thanks!
