I recently updated to the new bios, 1.30, that adds RAID support for the Thinkpad P50.
My P50 came with 2x pcie nvme 512gb m.2 drives. (I think they ship with the sm951, but not 100% sure)
Upon activating raid in the bios, I can select "M.2 SSD" as the mode, and successfuly create a raid volume from the 2 drives. The new raid volume shows up in the boot manager and appears to be healthy.
Macrium Reflect can even see and clone to the Raid volume.
However the installer for Windows 7, 8, or 10 cannot see the Raid volume. (Using a usb drive since i opted out of the cd drive).
I assumed this was a driver issue and proceeded to download basically every Intel RST driver I could find including the 3 on the Lenovo driver website and all the below:
64bit Intel RSTe AHCI & RAID drivers v188.8.131.528
64bit Intel RSTe AHCI & RAID drivers v184.108.40.2069 WHQL
64bit Intel RST AHCI & RAID driver v220.127.116.116 WHQL
64bit Intel NVMe Windows Driver v18.104.22.1682 WHQL
64bit Intel RSTe NVMe drivers v22.214.171.1242 WHQL for Win8-10 x64
RSTe NVMe 126.96.36.1995
Universal 64bit Intel RST Software v188.8.131.524
Universal 64bit Intel RST Software v184.108.40.2069
Even after trying every single one of these, I still can't get Windows to see the raid volume on install. I tried turning on and off secure boot, and CSM, but made no difference. There's really not many options provided in the Lenovo bios.
I've done a normal raid setup with HDD's on hundreds of computers, but can't for the life of me figure this one out.
From what I can tell this seems like it should be possible, and I'm pretty sure is even a configuration option offered by Lenovo.
Any help would be super appreciated!
Solved! Go to Solution.

If the ThinkPad P50 has Samsung SM951 NVMe SSDs, perhaps using the following NVMe driver from Samsung will work:
Samsung NVMe Driver Installer Version 1.1 - http://www.samsung.com/semiconductor/minisite/ssd/downloads/software/Samsung_NVMExpress_Driver_rev11...
Samsung NVMe Driver Installer User's Guide - http://www.samsung.com/semiconductor/minisite/ssd/downloads/document/Samsung_950_PRO_NVMeDriver_Inst...
As the User's Guide notes, this is actually for the 950 PRO, but I'm wondeirng if it will work with the SM951 as well.

Did you slipstream the Intel RST driver into the Windows 10 installation media? I had to do this when I was creating a WinPE USB for my P70. Otherwise, I suppose that you could create the install on the HDD and then move it over to the RAID 0 array.
The M.2 SSD's are SM951 BTW. I assume that you have initalized the RAID 0 array as GPT before trying to do the Windows 10 install.

Is this an install from a microsoft media or download, or is it from Lenovo recovery disks?

I did click the "Load Drivers" button during install, if you mean actually modifying the install image to include the drivers I did not. I actually thought the point of the "Load Drivers" button was to prevent the user from having to do that, however if that's the solution I might give it a go, I know it just takes a bit of time to get set up.
It sounds like what you did is similar to what I'm trying, I'm also using a usb. I actualy did trying installing to a HDD and then using macrium to clone it over to the raid volume, however I kept getting "boot device inaccesible", which appeared to also be a driver related issue, so I gave up on that route, assuming a clean install would be easier.
Lastly this might seem stupid, but I was under the assumption that as part of the windows install it created the partition table, I did not try doing anything special beforehand other than creating the raid volume. I typically use gparted for that kind of thing, but can't get it to see the raid volume either, have any reccomedations for that?
Thanks for taking the time to help!

OK, let's save yourself anymore grief. Go to this site and download the preload image for your system to a USB key and then start with the correct Windows preload.
Hope this helps.
