Hi,
Thanks for owning/ maintaing and sharing your work with us. Ended up here after buying a Toshiba XG5 OEM version for my Carbon X1 laptop (4th gen 6200u).
I have tried all possible drivers / settings (TRIMM/ windows caching,etc) but the results are very poor in comparison to all rave reviews of the drive (not mentioning Toshiba specs).
Really wonder how genuine those are while there are quite a few!?!?!
Anyway I will share my results maybe someone benefits from my experience before I give up/ sell it and go gack to Samsung - which I did not want - but the pm961 256GB is way better on any platform tested even with windows driver.

Test platform: Asus z170i Pro Gaming - latest BIOS, i3 6100, 16GB DDR4, Win 10 Pro uptodate.
The tests on Lenovo Carbon X1 4th Gen were a lot worse so I just tried the desktop thinking my lappie is broken or by default it is in RAID instead of AHCI - which is not.
I have tested it on with Microsoft Old Driver - stornvme, XG3 Driver, XG5 modded driver you shared.
If you still have any suggestions on how to get it properly working I am open to any. I have even installed a Ubuntu to try to bench it out and see how Linux deals with NVMEs but it'll take a while until I get the results.

Thanks
*PS I still haven't tried RAID and installing win RST drivers, but that circumvents the purpose of the drive because I can never get Intel RST installed on my laptop whatever I do ...
OR Maybe my results are normal so I close the case and give up. Might as well buy a 1TB SSD at the same price, probably, I could never see the difference in real life scenarios. Just pissed for having a Ferrari on paper while using it as a Hyundai - no offense to the car owners.

@Fernando Thank you for input. I will try all of that in another clean install. I might be doing just for the fun and repost... too bad for Toshiba not releasing good drivers because this NVME looks so promising on paper and very good for a laptop where power consumption is important.
this is why samsung is where it is and it might be worth buying their drives. They just support them and they work without too much fiddling.
Thanks again

This one worked for me: 32bit AMD SBxxx AHCI compatible RAID driver v3.3.1540.33 mod

Controller hardware ID: PCI\VEN_1002&DEV_4391&SUBSYS_B0021458&REV_40

I can see that you want the AHCI controller hardwareID and not the IDE controller hardwareID, as those are essentially two different pieces of hardware.
And I cannot see the AHCI hardware without a driver. I won't put them in my Win7 installation until I can get it working in my Windows XP...

If you give me the HardwareIDs of the IDE Controller, I may be able to guess the HardwareIDs of the AHCI Controller.

@Fernando Hey there... I have an doubt about one of the SATA CONTROLLERS on my AORUS AX370-GAMING-K5... It seems that the chipset SATA Controller is DEV_43B5... I haven't found a single AHCI driver that matches the HW ID... The second SATA CONTROLLER is DEV_7901... But I believe that controller is only for the 2 SATA EXPRESS ports... I have really, really shitty performance and 35+ sec boot with my Kingston Savage SSD & both of my HDD's... Obviously my main concern is with the SSD... Any advice is very much appreciated!!! Thx on advance!!!

@Fernando
Here's the complete HW ID...

Hi,
I read that Samsung Magician is not compatible with the OEM Nvme drives such as the sm961. Is this accurate?

Thanks

At least the driver works. Thanks.

Fernando,

My PC has Win 7 x64 Pro OS, instaled on : MyDigitalSSD 240GB M.2 PCI Express 3.0 x4
(PCIe Gen3 x4) NVMe SSD - MDNVME80-BPX-0256 {PHISON E7 Controller}.

SSD is intalled on PCIe adapter. Motherboarsd is Gigabyte GA-H97-D3H
I am planing to add a 1Tb SATA SSD soon.

Wich NVMA & ANCHI drivers do you recomend for it?

Thank you Fernando.
