thanks for running the M4 testing Ao1. I knew it was CPu intensive, but man it really doesnt use the HDD at all. There is a app that does it with a Nvidia GPU, called badaboom. It is supposed to be the fastest (of course it uses CUDA and the amount of cores on your gpu) i wonder what disk uasge would be using that.

@Timur-interesting. Could it be that readyboot is disabled automatically when an SSD is detected? We know that MS disables some features when it is detected, but i think it is fuzzy as to all of the things it disables. I guess one would have top watch the boot process with a HDD then compare to a SSD?
