@Steve I love the utilities you write, with their 20 KB, etc. executables.
Here are results on an AMD Radeon R7 SSD which is several years old as well as a couple of "spinners". The SSD is a little slow up front, so I'm running SpinRite Level 2 on it to see if that improves things. I noticed the progress bar pausing a few times when running readspeed. If not, I'll run a SpinRite Level 3 on it and see what happens. That will, unfortunately, use up a complete write cycle on the drive, so I don't want to do that often.
If my spinners are typical, it looks like the speed at the front of the drive is twice the speed at the back of the drive.
