I just ordered a 28core, 96GB ram, 256SSD (ergo why I need a PCI solution for storage), 580x, wheels (which annoyingly delay shipping by like 5 weeks, for freek'n wheels) 7,1 Mac Pro.
So for storage I thin I'm going with this:
Option A
Highpoint 7120 U.2 card. $400 bux:

And the 15.36 TB NVMe U.2 Micron 9300 pro drive. $2400bux:

The micron reads/writes at around 3500MB/sec. The Highpoint in theory would let you raid up to 4 of those together for 60+TB of SSD at probably over 12GB/sec throughput.
Option B
Another option is this Squid that takes 6 NVMe sticks (so you could fill it with 6 2TB sticks for around 12TB and reportedly around 12-14GB/sec read writes:

Thoughts
I think I like the U.2 form factor better. Not clear if either of those solutions will let you boot from a RAID, but from another thread, it seems you can at least boot with a single drive on the U.2 solution:

TLDR; Anyway, what was the config you ordered and what do you plan to do with regard to PCI SSD storage for your new 7,1 Mac Pro?
Update 2020-02-02:
Just thought I'd update this thread in that I went with the Highpoint 7120 and Micron 9300 Pro 15.36TB drive option. Lot of details of getting it to work found in this thread:
Ok so I got the drive. I got a bracket and it all seems to fit in decently tidy. Some pics: So I have the Pegasus J2i in there. Swapped the useless 8TB for a 16TB spinner. I got a 3.5" to 2.5" bracket. One note, the screws in the J2i that hold larger drives, are too big for both the 2.5"/3.5"...
