Purchased big new storage upgrade, please help me optimize my workflow!

     I have just purchased a few new external SSD drives including a new 20TB G-Raid system and I am looking for any assistance/ guidance in optimizing my drives to increase the speed of my workflow.

     I run a video production team and do a lot of editing (mostly testimonials and quick edits to 45 min presentations) and was experiencing bottlenecks that slowed my production which is why I made these big investments in expanding my storage.
