I finally found and fixed the issue ! Yay me, guess i wont return it anymore.
After i tried several other benchmark tools just to confirm me that my write speeds are shiet, i launched AS SSD ( forgot about it ) and after doing the tests, they were still low on the writes (reads too but not so much as affected as the writes), then just in that little window of information in the program itself it said "31K bad, under offset alignment@4k and i immediately recalled that i used earlier in the day Easeus partition master to wipe/format and even clone the disk (but i cancelled in the last minute) then i used windows own self partitioning and format and i guess something went bad over there
After i aligned the partition back to health (using a free app called minitool partition wizard) i redid the tests on CrystalDiskMark and AS SSD and voilá: the manufacturer marketed speeds were there !
I was just asking because I can't imagine how you'd use 32 queues with a single thread.
Obviously your casual user wont use those settings, but if the benchmark boast it in the first place, i guess most people will look at that number and say " wow good numbers".
