Please fix the seek time numbers - they’re wildly in accurate; full platter seek is more like 20-25ms. I tried chasing down where the 8ms number came from a while back, and I think it applies to old sub-100GB 10K RPM high-speed drives from 25 or so years ago, which were purposely low density so they could swing the head faster and less precisely.
