What happens if write cache flushing is disabled in Windows 10 ?

[deustroop]

I can see various posts giving the function of flushing but cannot find numbers showing whether disabling the policy ( device manager/disk drives/ properties/) affects performance. So I disabled flushing and compared scores in Samsung Magician for three drives, the 850 EVO, the 850 Pro and the 950 Pro. The results for the 950 were positive and for the others were mixed.
950 Pro enabled/disabled
SeqRd 2098/2119
SWte 935/957
RR 158320/167328
RW 81546/81603

850 Pro
SR 560/561
SW 531/530
RR 97937/97614
RW 85391/85940

850 Evo
SR 547/548
SW 520/526
RR 96958/97578
RW 83530/83655

Any info on the discrepancies in results ? I am inclined to disable flushing on the 950 and leave well enough alone on the others going with the default of enabling the flush.
Am I risking too much ?

There is so little difference, you will never notice in real world use so don't disable flushing.

As long as you have a UPS and don't store priceless data on it, I don't see a problem.
