Yes, that will likely be it. Some manufacturers have their own drivers and don't use the native MS driver.
Let us know how you get on.
Microsofts new native NVME driver - IO improvements
- Thread starter sityeuropa
- Start date
Let us know how you get on.
The main benefit for the everyday user is probably less CPU cycles resulting in less power draw/noise due to the lowered driver overhead. Higher IOPS won't benefit non-compute or non-storage intense operations (versus the likes of virtualisation, file storage, and so on which would see big benefits).
If anyone wants to spend their Christmas eve measuring some things, feel free and let us all know! Unfortunately, I'm going to get into the real Christmas spirit in the next 10 minutes!! See you all soon. Have a wonderful Christmas.

still no joy with get guid cmd
device manager shows 4 nvme controllers
with the stornvme.sys drivers
but the drives themselves drivers are still disk.sys
not nvmedisk.sys
oh well had enough for one day
will try again later
enjoy your xmas

Hope you had a good Christmas!
The drivers listed on the SSDs with the NVMe native driver activated are:
EhStorClass.sys
nvmedisk.sys
partmgr.sys
They should also show under a new tree class in device manager called "storage disks." stornvme.sys appears to be the legacy driver that interfaces with NVMe via SCSI.
If the WMI query is not returning any result, then your OS is not utilising the native NVMe driver for one reason or another.

Yeah still no joy
Even adding the reg entries manually
Not a total surprise given i have a complicated
Disk set up
Last attempt at running the guid command
Gave an error which I forget
The actual wording
But something along the lines of
The powershell file is in the specified location
But you're not allowed to open it
Do you want to do something which I totally forget
But has option for Y or N
Choosing Y still does nothing
Think I have
Ehstorclass.sys
Nvmedisk.sys
Partmgr.sys
And also a 4th one possibly stornvme.sys
No new tree class in device manager called
Storage disks
Thought in the last few days someone might have
Confirmed the guid question for you
Since i obviously am not getting anywhere fast
