I just Installed a Samsung 970 pro m2 NVMe blade in my 2012 MacPro running Mojave. It works fine. I have been running the ”Old” type of m2 blades for several years with no worries. I have had my system drive and my audio drive on two pci adapter cards and the third PCIe slot holds my HDX card. Now, I got something like 1100-1200 read speed and 700-800 write speed from the old blades. The new one gives 1400/1400, but it is speced out to deliver read speeds up to 3500. Is the MacPro PCIe bus slow or do I need a better PCI card to hold the m2 blade? I tried to google it, but found nothing. Not too many people do this I guess. :)

For comparison, SSD drives max out at 240-250 because the SATA bus is that slow in the MacPro.
