Question Problems with my samsung 990 pro 4tb

[adirna]

I just got my samsung 990 pro 4tb 2 days ago and i have few problems , first of all when i do benchmark on the samsung magician software
im getting way lower results then what samsung publish for this drive .
they say its should give

RANDOM READ (4KB, QD32) 4TB: Up to 1,600,000 IOPS​

RANDOM WRITE (4KB, QD32) 4TB: Up to 1,550,000 IOPS​

im getting way lower then that , so i wonder if there is a problem with my drive ?
im adding photo on this link since its not letting me to add it normal : https://prnt.sc/Os0y00Uvnqmg
as you see im getting like half of what i should get on random read/write , why is that ? how to fix that ?

my spec is 12600k ,rtx 3080 ,32gb ram and ofc i have gen 4 nvme slot.

Question - How to use IOMeter like Tom's for pSLC testing ?

If there's a page already written about this, apologies and I'd like to read it. The "how we test" article doesn't mention it. I found a post from 2023 here, but nobody actually gave information on IOMeter as Tom's uses it. What are the test methods used by Tom's for IOMeter to test the pSLC...

"tl;dr: Splitting an SSD into multiple partitions results in the pSLC cache size for each partition being split proportionally as well."

I did not know this happened.
But strongly suggests not to partition an SSD into smaller parts.

so you think that if i will remove all the partitions and put it on 1 drive only i will get the full speed? i mean to do it i will need to format the drive complitly and lose all the work i install windows and programs and games on it , if it will fix the problem i dont mind but if its not then all my work going to waist and will need few hours to do it again
