Extremely slow results from Samsung 980 m.2 SSD

hmm thanks for the feedback. i guess this is something that i need to fix somehow. i do not how to solve yet because i am using a workstation hp laptop and two m2 ssds are inside the laptop, there is no place to install a heat sink.

I will think about to cool my ssd. If you have any ideas, would be great to hear.

THanks.

Below is samsung 980 1tb and not expected plotting times.

below is another ssd with acceptable results.
