I think he was asking what the Blackmagic benchmark says for each drive if you remove them from the RAID0 configuration and benchmark them individually.
Yes. I want to see how broken the g2x1 controller is. Does it always report g2x1 or can it switch to g2x2 in a different slot or computer? If the card is new, then it should be replaced.

Corrected my read MB/s expections at #3,298 . Basically, the g2x1 controller will limit a 540MB/s SSD slightly (down to 450 MB/s) so maybe it's not too bad?

I destroyed RAID0, but the result is the same in the same slot.
Placed it in a different slot same result (pcitree1)

What does the Blackmagic speed test show for each disk?

313 MB/s is less than the 450 MB/s I expected but I think it's reasonable for the broken gen 2 x1 SATA controller. AmorphousDiskMark.app would return slightly higher numbers. If you can't replace the card, then maybe resoldering can work.

What do I have to re-solder?

The second PCIe lane between the bridge and the SATA controller that is running at x1 instead of x2? I don't know where.

Perhaps I will get a MacPro 6,1 in the next time and i want to upgrade the SSD to 2 or 4 TB. Which SSDs are good and available for the 6,1?

Are there any jumpers on the board? Maybe the number of lanes can be configured with a hardware jumper? Or, is there some sort of configuration software tool? Maybe the number of lanes used can be configured with software?

Avoid the Samsung 980 PRO, I had difficulties with Monterey 12.6.1 and Ventura. I am currently using a Kingston Fury Renegade 1TB.

Hi!
I want to install this SSD on my mac pro 5.1, which controller should I buy to make the most of the SSD's features?

A PCIe v3.0 switched card, any on the first post listed as compatible, like HighPoint SSD7101A-1 or Sonnet M.2 4x4. There are also cheaper/slower cards, like Startech PEX8M2E2.

If you did not buy the 980 PRO yet, go for a 970 EVO Plus instead, where you don't need a PCIe switched card to run it and even a cheap dumb adapter works.
Can you suggest me some adapters that you have tried and that work without crashing the operating system?

will only the listed nvme´s in post #1 work as osx bootdrive or as data drive in a Mac Pro 5,1?

It would be impossible to make such a list. If an nvme is not listed in post #1 then it might work or it might not work.

Thanks for your answer. I was just wondering if the listed nvmes will be compatible as a boot or data drive?
For example wd black 770 is listed as incompatible. But will it nonetheless work as a data drive if i put it into an nvme pcie card?

It says "multiple reports of KPs when in high load" which probably refers to load after it's booted in macOS. I would not trust it. Maybe try it in a USB 3.1 gen 2 enclosure if you want to use it for data. It will do ≈1000 MB/s with a good USB 3.1 gen 2 card, such as a Titan Ridge Thunderbolt 3 add-in card.

Sure. Good point. currently i use a 1tb 970 pro as datadrive and would like to replace it by a 2tb and cheaper nvme and put the 970 into a nvme enclosure. But
Instead of a titan ridge i went the usb-c card route, wich ofcourse will limit the speed of my 970 even more. But this is ok for me as long i get constant read and write speeds at arround 900 mb- as external ssd thats better than the samsung t7.

Ss a 970 pro replacement I know the evo plus is a potential candidate but from what i read it can get quite hot and throttles after arround 100 gb … so are there alternatives in that pricerange that dont slowdown the write speed?
