Thank you, Walter, for taking the time to provide answers to all three of my questions.
I have one follow up question: If I set the cache in After Effects, Premiere and Photoshop to the new external SSD, will the media files themselves, stored on the (unsplit) Fusion Drive, be the best case scenario, or should the video/photo files be on a second external SSD for optimum performance?
Thank you, again.
Will H.
