"A few tenths of a second in each service time benchmark might not seem like a lot, but over the course of a day, they add up. Admittedly, choosing one SSD over another won't double your productivity. Would you turn down an extra 10 or 20 minutes of getting stuff done, though?"
Your reaction time is around 150-300ms, so having an SSD that is 200ms slower than the fastest SSD is not going to slow you down the least. It won't even give you 10 seconds of extra "getting stuff done" over a whole workday unless your work resolves around only opening and closing applications.
It might maybe save you 2-3 seconds when opening large Photoshop, After Effects, Premiere or Resolve projects, but as a video editor, I know you will most likely be working on the same project the entire day, and if you're opening many projects per day, they are usually rather small and thus will load in a blink of an eye.
