OptiPlex 7040 Mini Tower upgrade with Intel NVMe 760P SSD

I have successfully fitted the WD black SN750 to Optiplex 7040 SFF.

Interestingly, since fitting it the Dell driver detection tool caused blue screens afterwards where before it did not. 

Removing the dell driver tool resolve the issue and it has since worked fine. 

I have found that I am not able to achieve the speeds the drive suggests it can with the 7040.

I have considered buying a PCI-e port to M2 adaptor to see if it helps but it's more money so haven't bothered. 

Hi there,

I also have a WD Black SN750 512GB on the Optiplex i7 7040 MT and getting similar speeds on the NVME port compare to the PCI-e 16x adapter:

Hey 

whooooooosh !

do you feel it would be the same on SFF?

..also is the on board NvME bootable for a fresh installation of Windows 10 pro?

Thanks you

What are your read and write speeds? 

I have a 7040 MT i7 6700 and I recently installed a Samsung m.2 nvme 970 Evo Plus 500GB and I never go above 850 read and write. It's spec'd at max 35k. I've read other posts about people having experiences like mine. I just would like to find out if there is some nvme out there that can give me more power is all. TKS for your time. 

Did you happen to install NVMe ssd in a PCIex1 adapter?

If so it would seem to have 25% of full bandwidth of PCIe x4

25% of 3300 = 850

970 EVO Plus SSD’s NVMe interface (PCIe Gen 3.0 x4 NVMe 1.3)

Sequential read and write performance levels of up to 3,500MB s and 3,300MB s,
