On fresh install, it's fine, but in time it gets worse as more deleted files needs to be trimmed and it's not working properly.
I tried to install the new firmware 4B2QEXM7 today via Windows with Samsung Magician, I was surprised it even showed up connected via my Titan Ridge in an OWC thunderbolt 3 ecnlosure and its formated in APFS. It said the firmware is up to date version 2B2QEXM7. I have had a lot of issues with the drive running Big Sur. I formated it and created 2 partitions one 500 gig for mac OS Big Sur and the other 1.5 terabyte for scratch disk installed in a single M2 pcie card. But Mac OS has not been stable, boot time is normal, but sometimes the finder just disappears and Pro Tools just locks up when I hit play on a session. I am wondering if the partitions is what my problem is as others seem to use the 970 plus as boot drives. When I use the scratch partition and run my OS off my other drive I have no issues, its just when the OS is running off the 970 plus that things are not working as they should.
How is it again – can you do the firmware update without erasing the drive? Will it be recognized in Samsung Magician in Windows even if the drive is APFS formatted with MacOS installed on it? Don't remember – it was so long ago I did a firmware update in Samsung Magician.
Not true as i have the vertical box and I won't update the firmware - mine has the Phoenix controller, I understand the 4xxxxx firmware is for the Elpis controller. I did see a report where it said the 4xxxxx firmware was for some versions with issues.Firmware update is only for the new hardware revision. Easy way to tell is looking at the packaging that it came in. Left (horizontal) is older while right (vertical) is newer revision. I have the older (horizontal) and it doesn't update the firmware either.

May I ask which version of Samsung Magician you have? I have 7.0.1. Seems some 970 EVO can't get later than version 2 of the firmware. ?♂️Today I finally managed to put a windows 10 installation on a USB drive via rufus (unbelievable that by default, windows is not able to install to a usb storage device...)
Now I was able to run Samsung Magician on my iMac2019 with internal 970 EVO plus (3B2QEXM7).
As I already knew, this is the newer (elpis) revision and Magician correctly indicated an update to 4B2QEXM7 which finished successfully.
I will now try to fill the drive with old data and delete it again to test whether I find any difference...
I also used 7.0.1, which should be the latest version at this time.
OK, that's not very good. Would it be possible to lower the SetApfsTrimTimeout value from the value set as default and get both faster boot time and TRIM enabled?
?
My understanding is that you either disable it to get normal boot times or enable it and experience much slower times. The bug seems to be in the TRIM implementation by Samsung, so whenever it's on Monterey will take a long time to boot.OK, that's not very good.

Well, your drive still supports it. Doesn't mean the OS will necessarily enable it though.
So there's no substance to this from a Reddit comment?
I've been using my 2T for a few months now without issue, boot times are normal about 20 seconds after boot chime with Monterey 12.3.1 I tried to update the firmware in Windows using the samsung app but it said there was no update available. I have seen reports of slow boot times but so far so good. Getting around 1350 write and 1500 read. I partitioned it 500 gigs for Mac OS and Data and 1.5T for scratch disk.
Unless you are using the OWC Envoy Express TB3 case which has caps at those speeds, you are only getting only just over half of what the write/read speeds should be on the 970 EVO Plus with other TB3 cases or internally, or with a Windows machine.
