Sorry to bump and old post.So it sounds like the Asus Hyper 16X card will not work for a raid. but since intel opened up X299 VROC for non-INTEL DRIVES. does that mean one can raid if the ssd are connected to the m.2 ports on the motherboard?
Intel opened up PCIE bifurcation. So what that means is that if you use a AIC like the HyperX16, all 4 drives will show up in windows.
And you can do a Software Raid, which i saw a limit of about 7-8GB/s with 4 Samsung 960 Pros of 512GB. and not bootable.
For real Vroc, it is still locked, and will only work when you use INTEL Drives ON X299 PLATFORM. It will not work with any other manufactures drive on the x299 platform.
Your best bet is to buy a raid AIC like High Point SSD7103. Its x16 (4x4) and bootable Raid card.
