Becuase my computer was running out of space i decided to add an overpriced SSD. My case has very poor airflow (no additional fans installed yet) i decided against the more expensive and hotter running western digital SN850 2TB. I cloned the old windows 10 disk using the software sabrent provided but then when i started testing the drive it did not perform good at all.
It turns out for best performance you need to use the "defragment and optimize drives" tool in windows 10. I also changed the power setting to "ultimate performance". Results still wasn't good
I ended up contacting sabrent costumer support but the individual basicially told me to make sure Trimp was enabled (it was already) and use "defragment and optimize drives" (which i had already done). Then he basically suggested making a clean install of windows 10, well they never mentioned you had to re-install windows to get the performance you paid for.
I also tried moving a 139GB folder and it took 2 minutes and 45 seconds with 900GiB of Free space.
To test this i booted via my old slow samsung 850 evo and ran tests from there
It turned out however that he was simply wrong, my SSD was not functioning properly and the issue was windows 10

By checking the "Turn off windows write-cache buffer flushing" box you do however slighly increase the risk of data-loss in some scenarious but if you actually want to protect your data you should do an actual proper backup. This unfortunatily didn't completely fix the issue of inconsistent performance, the performance will still drop badly once the SLC cache is filled. To get to these settings search for "diskmgmnt" in the start manu and continue from there.
The time to copy 139GiB dropped down to 129 seconds (from 165 seconds)
Synthetic benchmark also improved significantly and results became less inconsistent
This is similar (still a bit worse) to what a professional reviewer got:

I noticed during testing that the randon write speed was CPU limited meaning you need a better CPU than r5 3600 to take full usage of the Rocket 4 plus 2TB
