Thanks for the quick reply.

That would be very helpful! The model name is:
SAMSUNG MZVLB512HAJQ-000L7
That is the OEM SSD named PM981.
This evening I will modify the INF files of the related 32/6bit drivers to make them compatible with the NVMe Controller of the PM981 SSDs.

Thanks so much, you are a wonderful person!

@all:
Update of the start post

Changelog:

  • Samsung NVMe drivers:
    • new: mod+signed 32/64bit Win7 Samsung NVMe drivers v2.3.0.1709 dated 10/12/2017, mod+signed by me at 01/04/2018
    • new: mod+signed 32/64bit Win10 Samsung NVMe drivers v2.3.0.1709 dated 10/12/2017, mod+signed by me at 01/04/2018

    • Notes:
      Contrary to the original Samsung NVMe drivers v2.3.0.1709 these mod+signed drivers (hopefully) will additionally support the NVMe Controllers DEV_A804 of the Samsung PM981 OEM SSDs.

Good luck with these Samsung NVMe drivers!
Dieter (alias Fernando)

@phrygn:
Just to avoid any misunderstanding: Modded drivers are generally not accepted by the OS Setup, if you have integrated them into the OS image or load them while starting the OS installation.
Although my mod+signed drivers have been correctly digitally signed, it is not easy to get them installed within the early stage of the OS Setup. Reason: The OS Setup doesn't accept the digitally signature of a Company (here: Win-RAID CA), which it doesn't know and whose trustworthiness cannot be confirmed by importing the Certificate (impossible during the OS Setup).
So it may be possible, that you have to integrate the MS NVMe Hotfix for Win7 to get Win7 installed onto your Samsung PM981, but you should be able to get my mod+signed driver installed once the OS is up and running (don't forget to import the Certificate before you start with the manual driver update).

Hi Fernando,

Thanks for your insight. I was able to successfully modify install.wim and boot.wim on my W7 installer to include your drivers (using DISM) and everything has been going smoothly so far. The "DISM GUI" offered by codeplex has a feature that allows you to force unsigned drivers. Just thought I'd let you know! Thanks again.

@Fernando

Of course i can do a Benchmark for you, which software do you recommend me? to do the benchmark.

@x58haze:
Thanks for willing to do a benchmark comparison. The best benchmark tool for such purposes is named "Anvil's Storage Utilities" (requires .NET Framework 3.0). >Here< is the link.

Hello Fernando,

I recently bought one ssd XPG sx9000 and intended to use with windows 7. Adata apparently only gives one copy of acronis to clone from one hdd to ssd, but I'd like to install directly on ssd since another disk isn't always available. I tried to load some drivers found here, but the ssd was never recognized. Later I found out MSI Smart Tool and was able to create an installer which was supposed to be ready for ssds.. and it recognize mine, but the installation was painfully slow, so I gave and installed windows in a regular hdd then cloned it to the ssd. I don't know if the performance is at it's best and if there are some issues starting programs due to the cloning aproach, so I wonder If I could get any help here to get a pure driver or at least someone giving ideas where to look for it.

@x58haze:
Thank you very much for having done the benchmark comparison tests and for the screenshots, which verify, that there is no measurable performance difference between the MS in-box AHCI driver and the mod+signed AMD AHCI driver v1.3.1.277.
Conclusion: Only the stability of the driver will decide, which driver is the better choice.
Remark: Very interesting for me is the fact, that all your 3 on-board SATA AHCI Controllers are listed within the "System devices" section of the Device Manager. Usually they are listed within the "IDE ATA/ATAPI Controllers" or "Storage Controllers" section.


@HotLobster:
Welcome to the Win-RAID Forum!

The choice of the "best" driver doesn't depend on the HDD or SSD model, but only on the specific on-board SATA AHCI resp. SATA RAID Controller shown within the Device Manager by its HardwareIDs (right-click onto the related SATA Controller > "Properties" > Details" > "Property" > "HardwareIDs").
So please post the HardwareIDs of your in-use SATA Controller and I will try to give you my recommendation regarding the "best" AHCI or RAID driver.

Regards
Dieter (alias Fernando)

Your welcome. Btw i can help you for further test if you want. Also wanted to tell you that I had to back to the Microsoft Ahci, because i was getting insane latencies on the storport.sys reported by last version of Latency Mon, over 2500us

@Fernando :

Thanks for the reply.
Apparently I was distracted enough to forget about installing motherboard's SATA RAID Controller. The only controller I had installed was this Standard NVM Express Controller:

PCI\VEN_1CC2&DEV_0340&SUBSYS_10931B4B&REV_00
PCI\VEN_1CC2&DEV_0340&SUBSYS_10931B4B
PCI\VEN_1CC2&DEV_0340&CC_010802
PCI\VEN_1CC2&DEV_0340&CC_0108



After that I looked for drivers from MSI and AMD, but they require amd catalyst and don't detect it, so I'll try a clean install. My real challenge still is doing a direct installation (or reinstallation) of windows 7, instead of cloning it from another drive.

@HotLobster:
On board of your ADATA XPG SX9000 NVMe SSD is a Marvell NVMe Controller 88SS1093, but Marvell hasn't (yet) released an NVMe driver, which natively supports this Controller.
Consequence: Only the generic MS NVMe driver is able to detect and to manage this specific Marvell NVMe Controller.
Since Win7 doesn't have any MS in-box NVMe driver, you will have to integrate the related MS NVMe Hotfix. For details please look >here<.

I have Windows 10 x64 on my laptop and this current driver version installed 11.6.0.1030 for the 'Intel 7 Series Chipset Family SATA AHCI Controller'

Hardware ID's:
PCI\VEN_8086&DEV_1E03&SUBSYS_10BE1462&REV_04
PCI\VEN_8086&DEV_1E03&SUBSYS_10BE1462
PCI\VEN_8086&DEV_1E03&CC_010601
PCI\VEN_8086&DEV_1E03&CC_0106

Is there a better driver available that I would benefit from using?

@Dime_Baggins:
Within >this< thread you can find the answer to your question.
At the bottom of the start post is a table with Intel AHCI driver versions, which I recommend to use with Intel 7-Series Chipset Mobile systems.
Alternatively you can use the generic MS AHCI driver, which is very good as well.
