NVMe throttling from 2GB/s to 0.5GB/s is usually not thermal, it is an SLC cache exhaustion that brings a drive back to MLC/TLC packing mode. One can get samsung pro or a similar ssd and it will retain 2GB/s indefinitely. On cheaper drives, having a lot of free space (i.e. slc cache) may help. Not sure though what process can generate such sustained write bandwidth beyond few things like copying or video transcoding.

Which is why I replaced the cheap drive in my build desktop with a Samsung Pro NVME. It made a significant difference.

Multithreaded builds (make -j 24) can really hammer the drive. Read and write interleaved, which uses up cache in both directions.

I've used their Pro NVME drives as my OS drive for the last few years. Never had any issues with read write speeds either
