OK, I try it soon!

@yoshmann:
Where did you try to activate the Write-Caching of your NVMe SSD within the Device Manager?
What does the "Policies" tab show after having done a right click onto the NVMe SSD (shown within the "Disks" section) and chosen the option "Properties"?

@Fernando:
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?

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.

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?

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!

@Fernando I guess there's not much else to do, but do you possibly have any insight?

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.

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.
