Some added info from a reply on another post.... trying to make this a single go-to post:
I did a lot of research and felt the Kingston engineers had something special in their design. Remember that there is a custom built controller in these M.2 SSDs (which plug into the passive PCIe adapter card that you then plug into a selected PCIe slot). That controller is in the little M.2 SSD itself, not on that carrier PCIe card. The Predator uses a "next generation" Marvell 88SS9293 controller that allows use of 4 total PCIe lanes rather than the 2 PCIe lanes that a number of other M.2 SSD AHCI controllers are limited to. Plus, there also is the proprietary Kingston firmware driving the Marvell controller.
I read up on the success of two people using exactly this Kingston device in their HP ZX00 series workstations and thus knew I had a good shot at success. I also read up on other AHCI controller based M.2 SSDs from other vendors such as Samsung where much machinations were needed to get those to work on recent ASUS motherboards. Not something I wanted to deal with, especially knowing of the success of those two other individuals (one in Italy, and the other from this forum).
So, that is why I am only advising this approach at this time. I don't mind dinking around, but not that much......
The HP workstations currently do not have a dedicated M.2 slot so you need the little M.2 SSD plus the PCIe adapter card to plug it in to. There are aftermarket non-Kingston PCIe adapter cards you could buy and attach the Predator M.2 SSD to, but I stuck with getting both as a single combined item from Kingston (SHPM2280P2H/240G). I only needed the smallest version.
