I wanted to post my experiences with putting the Micron 9300 Pro drives in a Mac Pro 5,1 since it looks like this discussion is only about 7,1.
Using both the Startech card and the Sonnet dual card, the 7.68TB model works fine, and gives around 1500MB/s read and write (AJA and Blackmagic). Except, oddly, if I put it in the x16 slot using the Startech card, I only get half speed. Just that slot. And the Sonnet in that slot is fine. Seems like it’s running PCIe 1 speeds. No trouble; use another slot.
Then the weird(er) thing. I decided to get the 15.36TB model. Installed, turned the Mac on, and... nothing. No chime, no screen. Doesn’t matter which adapter card, doesn’t matter which slot, doesn’t matter which 5,1 (I have two). Put the smaller SSD in and it chimes and boots. So I gave up and am going to use the drives in a Sonnet PCIe Thunderbolt chassis hooked to an M1 Mini. That works fine. I did not test on a Mac Pro 7,1.
Long story short: Micron 9300 Pro 15.36TB prevents Mac Pro 5,1 from booting.
Could also be firmware version now that I think about it. The smaller drives have 11300DN0, while the larger drives have 11300DR0.Thanks. That's super insightful and weird. I never tried my drive with highpoint in the 5,1. I do know that combo works in the 7,1. So interesting that there would be a variation just on (apparently only) the capacity.

Interesting. I guess I could try putting the older version on my big drives but I don’t think risking bricking an expensive drive is worth it. Anyway, I’m happy with my Thunderbolt M1 Mini solution. Seems stable so far, and actually a bit faster (over 2000MB/s, depending on which benchmark is used). Thanks for the research though. If I were you I wouldn’t update my drive... it may stop working in your 7,1!BTW where do you get the firmware updates for the drive. I tried on the Micron site but they seemingly wanted some kind of NDA or something. Weird.
Answering my own question. For the latest versions, they require you to do something special, but older versions you have free access.
For the DNO release:
Micron Technology, Inc.

The DRO release seems locked for now:

Do you by chance own a 5,1 / can check if the HighPoint SSD7120 + Micron 15,36TB will be a possible combo ?Thanks. That's super insightful and weird. I never tried my drive with highpoint in the 5,1. I do know that combo works in the 7,1. So interesting that there would be a variation just on (apparently only) the capacity.

The tests "mkush" made was with cards that does not have a PCIe switch (?), but the HighPoint card do have a switch - Maybe its different ?
Im setting up a 5,1 - Already got the SSD7120 card, and was planning to get (just now) the Micron 9300 Pro 15,36 TB as a fast and spacious end-storage disk.
Im currently running 2x "Add in cards", Optane 900P - 480GB as system disk, and Optane P4800X - 1,5GB as projects disk / scratch - Couldn't find much info / threads about Optane media in Mac environment, so basically had to get them and try - They both work perfect.
But the initial plan was to get the P4800X in U.2 format, and use it on the SSD7120, to get better speeds (now limited to gen2 speed 1.500 MB/s) - But happened to find a "Add in card" with some only 1 or 2% usage, for less than 1.000 Euro.
Anybody knows if there is any difference in latency between the PCIe-swich on "Mac Pro 5,1 motherboard" (slot 3+4), and the PCIe-switch on the SSD7120 card put in slot 2 ?
Can you raid0 all the slots and boot off a raid0 constructed drive?My SSD7103 with driver v1.1.26 appears to be working fine with Mac OS 12.0.1 Monterey. Yay!
