I have a 15" 2010 MBpro that can not even play 1080p video without stuttering/freezing. While waiting for a new release, I have been using my iPad to edit photos and make videos which has been tough since I much rather use the laptop. I ordered the new macbook 15" with 1tb SSD and Iam second guessing weather or not I should get the 512GB instead. (Obvisouly got the pro 460.) This laptop is really adding up fast. My question is for all the people that do alot of photo/video editing, do you use most of the built-in storage or mostly work off external storage? If you use external storage, do you find it slower when rendering photos/processing videos? (It will obviously be connected by usb-c) I will moslty be doing 1080p but may find myself experimenting with 4K with this new power.
