I got the RAID0 working with the software application. I ran the tests and was underwhelmed by the performance advantages. I returned everything to amazon. The literature and documentation about VROC is ridiculously inconclusive. There were things that I was able to do that the documentation said that I wouldn't be able to do. Take a look at Q17 at the bottom of page 3 of this official Intel VROC (Virtual Raid on CPU) FAQ pdf: So Intel's offical answer is "it might work, might not work. If you buy our key, you'll receive official support, but if not, you do so at your own risk." I packed both 512gb nvme SSDs and the ASUS pcie card and dropped them off at UPS for my return to Amazon. Probably going to get the 1TB SX8200 when the refund goes through, and then just forget about all this. x299 is trash. Going to start selling this stuff on ebay.
