Ok, thx
Fernanado, tell me where to find information or share your opinion.
1. Is it possible to raid 0 of two HHHL PCLe x8 ssd
2. What is better to collect for the system, so that the speeds are higher than 5000 Mb/s sequential read and there is a good random read speed.
A. One ssd HHHL PCLe x8 (Intel p4618 or Samsung pm1725b)
B. Raid 0 of the two Optane 905p / 900р
C. Raid 0 of two Samsung 750 pro
@Busido_RUS
Provided, that you haven’t meant a “Software RAID0” created by the OS, which is not bootable, here are my answers:
1. Although I haven’t tried it yet, I am pretty sure, that it is possble to create a RAID0 consisting of 2 Samsung PM1725b SSDs, but not with all mainboards.
2. I doubt, that you will get long-lasting sequential read speeds of higher than 5.000 Mb/s. Look >here<, what I got with my system. Since I don’t have any of your listed NVMe SSDs, I cannot tell you, which of them would be the best choice for your speed speculations.
By the way: Samsung 750 Pro NVMe SSDs do not exist.
Just for your information: Having done some tests with an Intel RAID0 array consisting of 2 NVMe SSDs doesn’t mean, that I seriously planned to use it for my daily work.
A good NVMe SSD gives the user a much better performance and shorter access time than any SATA SSD, but it is an illusion to believe, that the creation of an Intel RAID0 array consisting of 2 NVMe SSDs will double the speed while working on your PC.
You will only realize a speed gain while processing very large sized files, but the big disadvantage is the risk of a sudden loss of all data in case of a problem with any of the RAID0 members.
Please! Who know how to instal Samsung PM1725b 1.6Gb into Windows Server 2012 Standard.
OS determine device like PCI - device, and that is all. I can’t find driver for that OS…
Thanks.

Welcome to the Win-RAID Forum and Merry Christmas!
Please post the HardwareIDs of the in-use NVMe Controller.
Regards
Dieter (alias Fernando)
Dieter, hello!
My device ID is:
PCI\VEN_144D&DEV_A822&SUBSYS_A812144D&REV_01
PCI\VEN_144D&DEV_A822&SUBSYS_A812144D
PCI\VEN_144D&DEV_A822&CC_010802
PCI\VEN_144D&DEV_A822&CC_0108

@yura :
Thanks for the HardwareIDs.
To be able to add the support of your specific Samsung NVMe SSD by the mod+signed Samsung NVMe driver v2.0.8.1611 I need the following information:
- Which architecture (32/64bit) has your OS?
- Which is the size of the NVMe SSD?
I suspect, that you meant 1.600GB. Am I right?
- To which generation (HHHL or SFF) belongs your NVMe SSD?
Dieter, thank you for answer!
I have Windows Server 2012 Standard 64 bit.
You right about the size of my Samsung PM1725b. It is 1.600 GB.
About generation of device I do not know sertainly…
https://market.yandex.ru/product–tverdo…86271?nid=83821
Sorry, I find: Samsung Enterprise SSD, HHHL,
PM1725b, 1600GB, NVMe, PCE-e,
R5400/2000WMb/s, IOPS(R4K)
750K/135K, MTBF 2M, 3DWPD, OEM
@yura :
Attached is the requested freshly modded and signed 64bit Samsung NVMe driver v2.0.8.1611, which hopefully will work with your NVMe SSD and Windows Server 2012.
Don’t forget to import the Certificate according to >this< guide, before you are going to updated the driver of the NVMe Controller (listed within the “Storage Controllers” section of the Device Manager).
Good luck!

Thank you? Dieter!
Now I try it…
Edit:
Driver has install. But Start device is impossible (Code 10).
@yura :
That is a pity.
Please do a deeper look into the posts from other users, who had written their experiences with mod+signed Samsung drivers. Maybe you or another user with a similar problem can find a solution.
Dieter, thanks for your attention.
@yura :
Depending on the Windows Server 2012 Edition you are running, it may be better to install an NVMe driver, which has been designed for Win8/8.1/10.
Please try to install the related driver variant, which is attached.
Good luck!

Ok Dieter, I try it tomorrow. Thank you.
Dieter, hello!
I’m sorry but this driver also didn’t fit…
(Code 10)
My OS is Windows Server 2012 Standard.
Hello, I’ve got an Samsung PM1725a 800 GB PCI\VEN_144D&DEV_A822&SUBSYS_A801144D&REV_01 with Windows Server 2019 1909 (64-bit) running on a SuperMicro board H11SSL-NC. I already tried different drivers, is it normal that I’m unable to activate the disk write-cache in the device manager or is it driver related?
best regards,
Yosh
@yura :
I am sorry about your test results, but I obviously am not able to help you by simply modifying the INF file.
My advice: Use the generic MS NVMe driver.
@yoshmann :
Welcome to the Win-RAID Forum!
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"?
Happy New Year!
Dieter (alias Fernando)
Dieter,thanks for your attention!
I do not know where to get generic MS NVMe driver for my OS [ms server 2012 standard].
Wish yua all the best!
Happy New Year! 
Yura.
