Dude.......you have NVMe, i'm pretty jealous not gunna lie. But yeah this is actually a completely fresh new clean install of Windows 10 Pro using UEFI. I've reinstalled it numerous times trying to figure out why it will not function at it's normal speeds.
The cable i'm using is a SATA 6GB/s StarTech cable, which may be the issue (StarTech is junk most of the time), i'll swap it out when i get some time today.
And the drivers are actually not the generic windows drivers they are the offical Intel RSTe driver for SATA RAID is what got the drive to show and finally work this last time around.
I'll post an update here soon after i swap this junky cable out and retest.
I also have low hopes since HP's always have issues with our setups for some reason.
Not really holding much hope for the cable to be the culprit here but its worth a try.
There are various freeware system analysis programs such as Speccy, HWinfo or even HP's own Performance Advisor, which should show upon drilling down to the disk i) the drives max possible speed e.g. SATA3 and ii) what speed its running at. Both would be interesting to know for troubleshooting purposes. THe other thing to do would be to test a different SSD if you have one handy or can borrow one.
As for the NVMe I say it definietly a nice speed boost but in the case of the Samsung it comes at quite a high price. That said NVMe drive prices are falling (the Intel 600p drives look to offer good value) and speeds are increasing (e.g. Patriot Hellfire with 3000/2200 MB/s while still being cheaper than the Samsung).
I can confirm that the Samsung 950 Pro works fine in our Z420 machines as a boot drive but have not tested the others so one needs to do their research accordingly before buying. I am just using a cheap PCIe to m.2 adapter in the PCIe 3.0 x8 slot, also works fine in the second PCIe 3.0 x16 slot.
Depending on how much RAM you have it may also be worthwhile to set up a RAM drive - it will save some wear and tear on the SSD and offer much higher speeds - pretty useful when downloading installers and playing around with large files or doing various operations on a large group of smaller files.
