Ok ran some tests with a 1TB 980pro on my old Kryo M2 evo dumb card in slot 4 and i got 1439 write speed and 1514 read speed, and all seems stable. if there were problems it seems the latest firmware has fixed it. I ran it several times and same results with in a few points.

It's not the speed, but warm boots and sleep. Did you restarted, went to sleep and back sometimes? A friend had several KPs in a month with sleep enabled and had issues when warm booting from time to time.

I did restart it about 3 times, no issues but didnt let it sleep, just ran the bench for 20 mins. all seems fine, maybe the firmware has fixed it. i had to update both the 980 pro drives as samsung majic said new firmware, i did it on a PC.

980 series issues with MacPro5,1 are insidious, it's not a problem that you get immediately and that's why we didn't add it to to recommend list yet. I really hope that the new firmware solved the incompatibilities, but I won't recommend it to anyone without a PCIe switched card until people test it over an extended period of time.

I use them in a switched card of course, so haven't found any issues. but hopefully the 980pro will also work in the dumb cards now with firmware update. I am sure more info will come apparent over time. I guess the previous info on the cards would put potential mac pro user's off buying them just incase of issues.

Besides the Samsung 980 series problems with PCIe v2.0, there are also issues with the TRIM timeout at boot time when using APFS because the Samsung controller takes too much time to clean/dealocate blocks, a problem that is happening since SM951-AHCI and affect several models with different intensity, worst offenders being PM981, the SM951-AHCI line and the 960 EVO.

My 970 PRO also suffers it from time to time, but it's tolerable without needing to disable TRIM or apply any workarounds like SetApfsTrimTimeout, while the SM951-AHCI becomes practically unusable after it's full and erased a few times.

Its strange, but very good reading.I have a 500G western digital black 750 M2 drive. now they say compatible, but mine is so strange, one minute it will write 2500 and read 2500 plus, 10 mins later it will write 1000 but still read 2300 . re boot and its back to full speed, leave it an hour and it might make 1000 write. the samsung 980 non pro is also variable on its write performance. going down close to 1000 write, read about 2000 this is all in a mac not checked with PC

both are firmware updated. So for me the western digital black 750 is the worst drive performance wise. all were new drives also.

WD/SanDisk are known to use the same model nomenclature for completely different blades, a thing that Samsung and Kingston were also caught doing, see the new 970 EVO+ and the NV1.

Cache design/behavior also greatly affects the write speed, Samsung drives seems to have a very decent write cache management algorithm, not totally perfect, but really above the rest of the market for the old EVO+ and all Pro models.

Just wanted to report XPG Gammix S50 Lite 1Tb and SX8200 Pro 1 & 2TB working great in Mac Pro 5,1 12 cores X5690
Crucial P2 1Tb working also great in 5,1 6 cores W3690

Hi all,

Just to share that a mac pro 6.1 works fine with a samsung 980pro and a nvme adapter of course. I know you will never get the PCIe 4.0 speeds but compared to the original Apple ssd the write speeds increased from 1047 MB/S to 1328 MB/S which is a win of 281MB/S

At the same time I've upgraded the processor from a E5 1620 v2 to a E5 2690 v2 which is a remarkable upgrade especially for the use in a music studio with logic pro x.

Cheers

Chris

Been looking for data on the enterprise SSDs of samsung: https://semiconductor.samsung.com/ssd/enterprise-ssd/pm1733-pm1735/

Anyone tested these on a Mac Pro 2019? Could not find any information on these...

Thanks!

ADATA and XPG also, the XG8200 Pro 1Tb and smaller models received a slower controller and memory in an unannounced later revision that’s about 30% slower…

Searched for SN520 in thread but nothing.. Anyone know if they work with MP5,1?

Also, what about the generic Chinesium 4x4 PCIE cards like this? https://www.ebay.co.uk/itm/194920707869 Wouldnt know what search terms to try and 122 pages (lazy!)

Entry level blades don't work right away or fail. You are buying a blade for a workstation, buy something tested.

Also, what about the generic Chinesium 4x4 PCIE cards like this? https://www.ebay.co.uk/itm/194920707869 Wouldnt know what search terms to try and 122 pages (lazy!)

If you read the first post, you would know that this type of card that requires PCIe lane partition/bifurcation is not supported with Macs.

Hi all,

Looking at getting this: https://www.amazon.com/CREST-SI-PEX40129-Ports-Bifurcation-Controller/dp/B07HYZY7P2/ref=sr_1_20?crid=2NXD9UK532NLR&keywords=pcie+x16+to+nvme+asmedia&qid=1651942885&sprefix=pcie+x16+to+nvme+asmedia,aps,128&sr=8-20&th=1

I saw in first post something about later versions not working correctly? Is this still the case? Was thinking of removing a 1TB SK Hynix P31 Gold from one of my laptops and getting that to add to mac pro 5,1.

Currently running generic adapter with SM951 512gb.

Hello,
I am thinking to remove my kryo M2 4x adapter for having a 16x pcie adapter .
My system is a Mac Pro (Early 2009) with 2 x 3,33 GHz 6-Core Intel Xeon Processor and Radeon RX 590 nitro+.
The adapter I found online in a very good price is this one https://www.ebay.de/itm/302455183732
If anybody has already used it I would appreciate an opinion.

Hello,

What you will gain with that?

A M.2 device can only connect to 4 PCIe lanes, or less. All M.2 adapters are x4, even if the card size/format/etc is x8/x16.

Dumb adapters are limited to PCIe v2.0 with a MacPro5,1, changing from the KryoM.2 to this other one will change nothing speed/throughput wise.

Thanks a lot! I was just wondering if this is a cheap solution for gaining a bit of higher speed of the Samsung ssd 970 EVO Plus

Nope, nothing will change, save your money and get a PCIe switched card like the ones listed on the first post of the thread.

A PCIe switch is needed to convert the fast/narrow M.2 slot (8 or 16 GT/s x4) to the slow/wide PCIe slot (5 GT/s x8 or x16) of the Mac Pro 2008 - 2012 or slower/wide PCIe slot (2.5 GT/s x16) of the Mac Pro 2006-2007.
That ebay item doesn't have a PCIe switch and therefore only 4 of the 16 lanes are connected and they can only run as fast as the PCIe slot supports (2.5 or 5 GT/s)
