Deathwish RAID racing; hit single channel DDR4 transfer rates with WD Black NVMe drives

This will cost you a bit to set up but will provide you with almost unbelievable transfer rates.  Simply combine eight 1 TB WD Black NVMe SSDs at roughly $400 a pop with a pair of ASUS' Hyper M.2 expansion cards at $60 each and build up a deathwish RAID of doom!  TechARP just posted a look at how Andrew Vo managed to pull this off. 

As pointed out by several readers who ... well, actually watched the video instead of just reading the article ... this was done on Threadripper, which makes far more sense than a PCIe lane starved Intel system.   Ignore me and make your Threadripper roar.

Unfortunately this trick will not work the same on AMD platforms, it is limited to Intel Skylake or Coffee Lake with VROC support.  It will be interesting to see how a properly configured Threadripper system would compare.

"To hit 19 GB/s, you need to create a RAID 0 array of those eight 1 TB WD Black NVMe SSDs, but you can’t use the motherboard’s RAID feature because you would be limited by the 32 Gbps/4GB/s DMI bottleneck."

Intel Quad RAID-0 Optane Memory 32GB Bootable Without VROC Key!

We've been playing around a bit with Intel VROC lately. This new tech lets you create a RAID of NVMe SSDs connected directly to newer Intel Skylake-X CPUs, without the assistance of any additional chipset or other RAID controlling hardware on the X299 platform. While the technology is not fully rolled out, we did manage to get it working and test a few different array types as a secondary volume. One of the pieces of conflicting info we had been trying to clear up was can you boot from a VROC array without the currently unobtanium VROC key...

Well, it seems that question has been answered with our own tinkering. While there was absolutely no indication in the BIOS that our Optane Memory quad RAID-0 was bootable (the array is configurable but does not appear in the bootable devices list), I'm sitting here looking at Windows installed directly to a VROC array!

For the moment this will only work with Intel SSDs, but Intel's VROC FAQ states that 'selected third-party SSDs' will be supported, but is unclear if that includes bootability (future support changes would come as BIOS updates since they must be applied at the CPU level). We're still digging into VROC as well as AMD's RAID implementation. Much more to follow, so stay tuned!
