Write cache buffer flushing disabled for NVME ssds?

So I was tinkering with my Intel 600p nvme ssd tonight, running crystal disk mark for benchies. I noticed that when disabling write cache buffer flushing in device manager, on the ssd, it gave me me almost 250mb/s on my 4KQ31T1 scores in CDM. Now I have always read the dangers of disabling that setting for a drive. But is this something that nvme drives should have disabled? That is a pretty big boost to get.

Write cache buffer flushing...enabled or disabled for nvme ssds? And is there Intel NVME drivers I should be using with the 600p? IRST are for sata based drives correct?

I have read a few forum posts that disabling it is a good thing for nvme drives. Recent posts, nothing dated.

What do you think?

Honeslty i see no boost there and I'm only seeing a small test variance . Which is normal for synthetic bench. In all honesty the 4k q32 bench means nothing on desktop usage.
 
If you're not concerned with data loss on the system, then go with whatever you like.

I agree with the above though...there's really no difference between those two test runs. You would never notice this difference in any real workload on the machine, until you lose power anyway.

Regarding your other question, the default MS drivers are fine for most NVME drives. You shouldn't need to install IRST.
