Just wanted to share the storage I'm running in my 2023 M2 Mac Pro, as others may be curious or wonder what works/doesn't work.
I have this setup, all working and recognized perfectly without any missing drives or other issues, also running on macOS Beta 15.1:
Bottom 16x slot has a Sonnet 4x4 NVME card with 4 NVME
Second 16x has a Sonnet 8x4 card with 8 gen 4 NVME
Slot 8x has an OWC NVME card with 4 NVME
Slot 6 at 8x has a Sonnet SSD raid card with 2x SSD
and then 2x SSDs with Sata with a Sonnet J3i
That's a ton of storage, all gets recognized without issues.
PCIe lanes and speed are of course dependent on what you are running. You cannot run the 16x slots at full speeds if running the other items, for example, but it will works fine.
Yes, my slot allocation in the expansion utility shows Pool A as 181% full and Pool B at 59%.
I use the majority of the large drive arrays as sequential Time Machine backups or manual mirror, meaning I'll only be using 1-2 at a time so speeds are fine.
I had a 2019 Mac Pro, so those cards worked great when moving over.
I tried a Mac Studio for a brief time, and it was a nightmare with clutter and tons of external drives for Thunderbolt 3, noisy fans, etc.
The M2 Ultra Mac Pro IMO for my use case is totally worth it - I also got mine around $1,500 off Apple's retail price, so not bad for fitting it all in, without desk clutter ha.
