Hi I'm new to Mac and I'd like to ask a question regarding Photoshop. I have 1TB on the hard disc, which is currently designed as a scratch disc (by default), and 1Tb of external drive that I currently use for storing miscellaneous items and as a backup. I would like to ask for opinion of someone more experienced - is it better to use an internal or external scratch disc for Photoshop, and if internal, is it better to create a partition or just leave things as they are. I feel I have plenty of space to do any (at the moment
). Thank you for help
