long ago I worked on a graphical tool that showed disk fragmentation. Of course all the devs would test on their various hardware, pre-SSD. It was true that you could change the performance for daily tasks by some fragmentation management.

In recent years I use Linux with default ext4 mostly. Linux and ext4 appear to me to regularly maintain the disk allocations somehow, but I do not have a graphical tool to show that; details welcome.
