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."
