Samsung 970 Evo Plus low IOPS after firmware update

I have a 970 Evo Plus 2TB and three 970 Evo Plus 500GB drives, all with low usage, barely any use on 2 of the 500GB drives and the IOPS are 270,000-300,000 for random read and 200,000-250,000 for random write after updating the firmware for all 4 SSDs, before the firmware update it was normal, over 500,000 IOPS 

When is Samsung going to release a firmware update to fix this? I have found others with the same problem online. 

I've tried all  versions of Samsung magician that are available online from 6.1 to 8.1 to test it. I'm using  an i7-10875H 8core CPU running over 4.5ghz, 32GB of 2933mhz ram on the  Gen3 (PCIE 3.0) NVME slot and I separately tested it on a 40GBPS NVME external enclosure using windows 10 Pro,  Firmware version 2B2QEXM7 on both the 2TB and 500GB drives.

My Samsung 980 Pro 1TB gets over 500,000 IOPS and up to 700,000, while my 990 Pro is over 700,00 IOPS on the same laptop. 

When I called tech support they didn't want to rectify or accept the problem but instead wanted to start the blame game.

It appears the iops speed was a trade off to accomodate improvements in security, reliability, and or compatibility.  If this is in fact the case then the choices moving forward are to buy higher performance drives,  suck it up,  or buy a different brand.

Over time my own Xeon machine has migrated from 960's to one 2TB 990,  5 4TB 990s and one different brand 4TB as a reminder to how good the 990s are.
