OK, I try it soon!
Thanks for the warm welcome, Dieter. Happy new year to you, too.
Under disk properties on tab policies, I’ve got an radio group with fast remove and better performance (selected). below is an unchecked checkbox with activate write-cache with the hint, that I cannot change the write cache for this device. moreover, the setting for disabling the write cache buffer flushing is greyed out and not selectable.
I mean, this is an enterprise ssd, maybe I misunderstood something. I just thought, I should have write cache, also. so is it a driver related issue or drive firmware or even mainboard related that I cannot use the drive cache for the nvmes like I can do for intel ssds and other.
best regards,
Yosh

Hi Dieter! How are you? I hope 2020 is going well for you.
On windows server 2019, the drives have a different hardwareID:
SCSI\DiskNVMe____SAMSUNG_MZWLL3T20B3Q
They act as if they are a SCSI devices instead of PCIe. It might be Storage Spaces playing tricks but I’m not sure.
Do you have any insight about this?
EDIT by Fernando: Unneeded fully quoted post replaced by directly addressing (to save space)
@setiron :
It is absolutely normal, that modern Windows Operating Systems see and handle the attached SSDs as SCSI devices.
This is good for the NVMe SSD, because the TRIM/UNMAP commands will pass through the NVMe Controller and will clean the garbage containing cells very quickly.
Oh I see, interesting. Sorry about the full quote, it was a bit excessive.
I’ll try your modded driver again and report back.
Cheers!
Hello, guys.
I wonder, do I need some specific driver for Windows Server 2019 (LTSC) and Samsung PM1725b 3.2Tb (MZPLL3T2HAJQ) PCI-E 3.0 x8 NVMe SSD drive?
I can’t find any driver for this server SSD on Samsung site, motherboard (I have a ASUS P11C-X server/workstation mb) recognizes and boots from it fine, windows server in installation stage also see this drive correctly. I use standard MS driver.
Thanks in advance.
@Gre4ka :
The NVMe SSD itself doesn’t need a third party driver. Only the NVMe Controller, which is within the SSD’s chip, needs an appropriate NVMe driver.
Why do you want to replace the generic MS NVMe driver by another driver?
To be able to answer your question I need the HardwareIDs of the NVMe Controller, which is listed within the “Storage Controllers” section of the Device Manager.
Yes, NVMe controller in SSD drive. I mean it.
HW ID of NVMe controller is: PCI\VEN_144D&DEV_A822&SUBSYS_A814144D&REV_01
What the benefits replacement of generic driver can get for this drive and OS? Why Samsung don’t offer special (maybe more fast etc) driver for it’s server products? As I see their usual consumer driver (v3.3 at the moment) don’t recognize any server drives. They only rely on generic MS driver?
The "pure" 64bit Samsung NVMe Drivers v2.0.8.1611 for Win7/10 x64, which I am offering >here< within chapter L, definitively should support these HardwareIDs. Don’t forget to import the Win-RAID CA Certificate, before you start with the driver update.
You should ask Samsung and not us.
Hello again,
it took a while before I could give the drivers a try, but I finally did.
Unfortunately windows (2019DC) isn’t able to load the drivers, error 10. Even after a reboot, which took a long time due to the drivers not loading, I had no luck.
Too bad, as I’m still unable to make windows see the drives’ PLP and thus cannot enable caching.
Thank you for your efforts though!
@setiron :
If I were you, I would try to get the NVMe driver of another manufacturer installed (e.g. the Intel NVMe driver v4.4.0.1003). You have to force the installation by using the “Have Disk” option and should disregard the popup warning.
Don’t forget to set a “Restore Point” before you test it!
I just got my hand on a PM1725b, then I noticed that the dell 2.0.8.1161 driver can run on this drive flawlessly with moderate performance gain.
Here is the dev ID for my 12.8TB drive. Hope there are users who can offer more HWIDs(for different capacity variants), so fernando and I could potentially add support for PM1725b into the HP+DELL samsung driver.
PCI\VEN_144D&DEV_A822&SUBSYS_1FF61028
Thank you.
@111alan :
Thanks for your contribution.
Since a matching thread (this one) already exists, I have moved your post into it. I didn’t see any reason for starting a new thread with a rather similar topic.
What do you expect from my side? For which OS do you want a freshly modded NVMe driver, which additionally supports the HardwareIDs PCI\VEN_144D&DEV_A822&SUBSYS_1FF61028?
Maybe it is not necessary at all to add the specific HardwareIDs, if the attached generic mod+signed Samsung NVMe driver v2.0.8.1611 should work.
Can you test it?
EDIT: Attachment removed (download link will be offered >here<)
Tested, it works correctly. This seems to be the win10 edition(modded from 2012r2 version). Could you also do a win7 edition(modded from 2008r2 version)? Thx.

@111alan :
Meanwhile I have additionally tried to make even the latest Samsung NVMe drivers v3.3.0.2003 usable with all Samsung and non-Samsung NVMe SSDs. The generic Win10 driver works fine with my Sabrent Rocket 4.0.
If you are interested, please send me a PM.

@all visitors of this thread:
JFYI: There are new mod+signed generic NVMe drivers available for users of HP and Dell systems, whose Samsung NVMe SSDs respectively their Controllers are natively not supported by the officially released NVMe drivers. The new drivers do support the NVMe Controllers of all Samsung and non-Samsung NVMe SSDs.
You can find the description of the freshly modded drivers and the download links >here<.
Good luck!
Hello,
do you know whether the new release works on windows server OSs? As mentioned during the last year, previous modded drivers did ncould not load and would give a code 10 device error.
Is it possible that you can add support for device IDs below, woud be much appriciated:
SCSI\DiskNVMe____________________________MS1PC5ED3ORA3.2TKPYA8R3Q
SCSI\DiskNVMe____________________________MS1PC5ED3ORA3.2T
