Sorry, I got news about new WD ssd (hope for updated SN550) 2 days ago and think that message on 1 page was about old product. WD line of drives really confuse me.
Great info, and appreciate the assistance!
Was pleasantly surprised that Sonnet provided an RMA well past 30 days on PCIe 4x4... I like Sonnet components and they've earned a major plus from me on a gracious return. I've ordered 2 HiPoint SSD7101A units and 4 more 970 EVO Plus 1TB to populate 2nd card. 2 MacPro 5,1 will have nice upgrades! The Sonnet did perform very nicely on 1TB, and super on 3x 1TB... sounds like the Highpoint will be similar in performance.
Thanks @tsialex
is a PC/windows machine needed to upgrade firmware for the Samsung 970 EVO Plus for it to properly work on a PCIe card as a boot drive?
(or can the firmware be done on a Mac as well?)

Samsung M.2 970 EVO Plus firmware upgrade problem solved
EDIT : If you buy a Samsung 970 EVO M.2 blade, install it but before formatting check the FIRMWARE revision in " About this Mac/ NVMe "first. It should be 2B2QEXM7. If it is 1B2QEXM7 you will have problems with the blade. ==================================================== I bought a 500gb...

The new performance king: Samsung 980 PRO. The Verge has a initial write-up about it, PCIe v4.0 with read speeds of 7,000MB/s, write speeds of 5,000MB/s. Starting at $89.99 for 250GB of space, up to 1TB for $229.99.

These are PCIe 4.0 SSDs
Pretty disappointing that they've done away with 2-bit NAND. These sound like PCIe 4.0 versions of the 970 Plus. I wish they'd at least kept the option for a pro-"Pro" model. Sustained write speeds still plummet as soon as the cache is filled.

On an unrelated note, I'm wondering if anyone could help me understand how JBOD can interface with striping (RAID 0)?
If I've got 6x 1TB drives and 2x 2TB drives, and I want to stripe them all together. Is it possible to use JBOD to turn the 6x 1TB drives into 3x 2TB drives, and then stripe those three JBODed 2TB arrays with the two natively 2TB drives - to create a striped 10TB RAID?
I've Googled up, down and all around, but can't find any clarity on the question.
SSD adapter drivers: In reading about these two cards: Highpoint 7101A-1 and the Sonnett 4x Silent card, it seems the Highpoint card uses drivers where the Sonnett card does not?
Or does each card need drivers for RAID, and no drivers if they are used as JBOD?
Or does each card need drivers for RAID, and no drivers if they are used as JBOD?
Does this would help to bring this flying in a 5,1?
Delock PCI Express x16 Card to 1 x M.2 Key B + 1 x NVMe M.2 Key M + 1 x mSATA - Low Profile Form Factor
I think Disk Utility can RAID together RAID drives so you can do that. You want each part of a RAID 0 to be about the same speed (i.e. if a RAID 0 has 4 disks and disk A is slower than the rest, then it would be like you were RAIDing four of the slow disks together).
I think the 2TB JBODs would perform almost as well as the 2TB drives so RAIDing them together should be fine.
Fingers crossed ? if I can use the 2x 1TB JBODs, that opens up the option of creating an 8TB RAID 5 (which would add the option of some redundancy in there, which would be nice).
Do benchmarks of the individual drives first. Then do a benchmark for the JBODs. Then benchmark a RAID0 of the two normal drives. Then three. etc. Then benchmark the final result. With all the numbers, we can see how the RAID0 efficiency changes. Then compare with RAID5 result.
Never, this card is a SATA M.2 + mSATA + PCIe (NVMe/AHCI) adapter, that will be limited by the x4 PCIe v2.0 M.2 connection (~1450MB/s) of the MP5,1 and needs two MP5,1 SATA ports to make the SATA M.2 and mSATA work.
This is what I call a extremely dumb product that only be useful to a small niche. Who has a SATA M.2 + a mSATA + a PCIe M.2 blade to connect at the same time, losing two of the Mac Pro SATA ports that could be used to connect hard disks or 2,5" SSDs.

AFAIK, none. While you can convert x16 PCIe 2.0 into x4 PCIe 3.0, the switch magic is limited by the PCIe v2.0 x16 total bandwidth. You will never get more than 6000MB/s real bandwidth throughput with a MP5,1, not even using a PCIe v4.0 switch.
Hello,
After staying on the old 5,1 Firmware that came with High Sierra I finally updated my Mac Pro 4,1 -> 5,1 to the 144 firmware that comes with the Mojave installer. So far so good but now I read in the first post that there is a difference in NVMe support in flashed 4,1 to 5,1 MP and native 5,1. Why is that ? I thought the 4,1 and the 5,1 are identical in hardware. NVMe stuff is still is new to me and I never owned one, so please forgive my dumbness.
thanks+

But shouldn't this be the 7.877 GB/s burst, or is the overhead in this PCIe 4->2 conversion soo badly? I guess it might be summing up...
PCIe 4.0 x4 is slightly less bandwidth than PCIe 2.0 x16. The only reason the MacPro5,1 is limited to 6000 MB/s is because it's old. Maybe a new computer with a new CPU could get 7000 MB/s from a PCIe 2.0 slot (a PCIe 4.0 or PCIe 3.0 slot set to PCIe 2.0 speed)?
Anyway, the Samsung has 7000 MB/s read but only 5000 MB/s write, so maybe the MacPro5,1 slot is good enough. No-one has tried a card with a PCIe 4.0 switch yet though. Are the Highpoint cards with PCIe 4.0 switch available yet?

Please read again the table of the first post, you are messing things. If you have 144.0.0.0.0 you have a MP4,1 cross flashed with MP5,1 firmware, so it's a MP4,1>5,1. The last MP4,1 firmware update is from early 2010, 6 years before NVMe spec. MP5,1 EFI firmwares support NVMe since 140.0.0.0.0.
Hello,
I just installed a 970 evo plus 2To in an I/O Crest pci 3.0 x16 to 2x M.2 adaptater ... in slot 3 and 4 i ve got 1500Mb/s
and in slot 1 or 2, i ve got 3500Mb/s but after 10-15sec of black magic or Aja test ..my Mac Pro 5.1 Freeze and restart.
I ve tried with a old AHCI samsung blade sm951 with adapter in slot 1 OR 2 and same thing happened ....I m under Catalina 2x5690 poco + 96 go 1333Mh + Radeon Vii + Pixlas mod. ANY IDEA ??

How about if you don't run synthetic disk benchmarks - any problems?
Same card, same SSD. A friend of mine, exactly the same mac as mine, 4.1>5.1, follwing my advice bough the same. In my Mac I have never had a problem, SSD and AHCI connected at the same time. In his, the Mac randomly freezes. Tried a second same card, and the same. Maybe they have changed something in the card?
tested with black magic disk speed test and Aja system, exactly same freeze and restart....now in slot. 4 sticked at 1500Mb and no freeze or restart.... waiting for a solution..."In the words of the late great "Groucho Marx"---Doctor, doctor, it hurts when i do this!!
