The larger take-away is how the hybrid offers a good cost/benefit ratio for anyone willing to swap for a different hard drive. While the SSD offers faster reads overall, the cost of hybrid drives win it over.
Course, I would love to see the difference between the stock 5400rpm (?) drive and a 7000rpm drive. Or even a 10000rpm for the fun of it. I still think the hybrid would still offer overall performance, but I'd love to be proven wrong!
I also like this video because it keys more into the demands and engineering for games which have a much higher data need than say a web browser or other application without high graphic needs. Nothing new to me as a video game developer, but I consider that knowledge more a privilege and love to see that kind of knowledge shared more!
