I'm thinking of getting the base Mini w/ 128 GB SSD (for OS and apps) and buying an external 1 TB SSD for all my files. My main uses for the Mini would be editing photos in Lightroom (~25 MB RAW files) and I've been doing some light video editing with 1080p files (though my camera is 4K capable and may go down that path in the future). I also do some light Photoshop and inDesign work. I'm looking at this external Samsung 1 TB SSD for $228... https://www.amazon.com/gp/product/B073H552FJ/ref=ask_ql_qh_dp_hza The price is GREAT. But is this drive more for storage and not actively working on my files? I'm guessing this external drive would be slower than a Mini with 1 TB internal SSD, but would that even be noticeable with my use (photo/video editing)?
