Same Machine different NVME makers Weird results any suggestions thoughts

[papa41652]

First off I know I dont have the best understanding of swar plot-manager and know i have some errors with the settings. That being said i get 18 to 22 plots in 24 hours. the only difference between the 2 are the plotting drives. getting swings of 2hours in plotting. The faster system A uses Sabrent 1TB Rocket NVMe. plot times are 06:35 +- 7minutes
Lets call the slower one B it uses the Inland Premium 1TB NVMe. plot times are 7:30 to 8:30 hours I have swapped the NVMe no difference. I thing i noticed faster system A will only get 5 to six plots running in different phases. The slower system B will get 6 to7 plots running. thought this would be a good discussion. Or do we just chalk this up to winning the silicone lottery

So 2 questions

Any thoughts on why the difference in plotting times
Any Ideas on what to change in the setting to optimize this setup
