I’m getting about 2,500 to 2,700 R/W on the Sabrents, and the HP EX950s are just a tad better Almost hitting 3,000.
Got a tip for us?

I’m getting about 2,500 to 2,700 R/W on the Sabrents, and the HP EX950s are just a tad better Almost hitting 3,000.
i only ever got a crappy phone pic of it, i ended up returning the drive and getting a corsair mp600 which I know works. Its nice and happy now. i buttoned back up my mac pro but I popped the drive in one of my hackintoshes and got the same error. 10.14.6

I had a similar question on the Sabrent but with the MP 5.1 with a kryoM.2 Aqua evo. Does the latest gold and previous dark blue versions of this blade work with booting? I'm going to say yes based on what has been documented.
I see on the front page the Sabrent Rocket (3D TLC NAND version) is called out but not specifically for the newer PCI 4.0 blade (gold) but it does say Phision E12 (dark blue) and the Phision E16 that's found in the latest PCI 4.0 (gold) product but only PCI 3.0 is mentioned on the page (strange).
Anyway, despite having an Evo 970 Plus in my PC, I can not justify the price when compared with either Sabrent model, as much as £200 (E12 version) vs. £380 (Evo Plus) between the two for 2TBs in thew UK - go figure.

How are you guys able to hit more than 2,000 tp 3,000 R/W for NVME? I only can manage to hit 1,500 or less with my nvme EX950 1TB? Thanks.
I think the challenge here is to get more than the bandwidth offered by a single 4 lane PCI 2 slot, i.e .purchasing an exceedingly expensive adaptor (10x cost of a 4 lane) with a PCI switch that does not rely on PCIe bifurcation to give you double the lanes or more and finding a spare x16 or x8 slot to plug it in to achieve what are already pretty super fast speeds. You can do the calculation based on the advertised speeds for PCI 2 vs. 3 and what the NVMe's advertised performance is. I guess you could also try and software RAID 0 across 2 cheaper 4 lane cards for significantly less money if you have the free slots to harvest the performance of 2 x 4 lanes.
Too Bad !
When I Insert second Samsung 970 EVO M.2 the carde is not recognised by Mac pro ?
Is it Bifluctration incopatibility problem or something else?
Maybe I havent enough power?
The card is recognised as X4 PCIe not x8 PCIe ?
Any advice will be healpfull.

The advice is to read and understand post 1 of this thread...
Are you talking about the product you linked at #2,077 ?
If the card doesn't have a PCIe switch then it is bifurcation and you can only use one NVMe.
macOS System Information.app does not show PCIe switches so you need to use ioreg or pciutils to find out.
Try pcitree.sh instead (follow the instructions at the bottom of the page)
A bash script to produce more informative output than lspci -nntv

This card will not work with 2 blades in a MP.
As mentioned previously fur further explanations see post #1.

Did you read post #1 thoroughly in order to understand that simple bifurcation controllers do not work with more than 1 blade and to run >1500MBPS and/or more than one blade you need one of the few PCIe switch controllers compatible? The section titled "Recommended PCIe adaptors for Mac Pro 5,1 & 7,1" might be of interest.
I also posted some feedback above on the topic. For a Mac Pro 5.1 I’d be hesitant to spend more than $30 on a controller and a couple of hundred on a 2TB NVMe blade. I would be very happy with 1500mb/s performance and anything more you’d have to ask what application use case warrants spending large sums on a 10 year old workstation. You can add SSDs or NVMe S-ATA adapter trays if you want more NAND capacity later with your 5.1, or a second controller as I suggested above (but not tried out) for $60.Thank you for response I have

I think you got a point about whether the speed improvement is worth the investment for an older Mac Pro.
I guess that's up to the owner.
Another (big) advantage of a multiple blade card is that it occupies only 1 PCI slot..
At first sight it sounds like a good idea to RAID 0 2 adapters with 2 blades...
But then RAID is not (natively) supported as a bootdrive for modern OS, so you'll have to install another blade with the OS /put the OS on a SATA2 SSD/HDD/ invent another solution...
Another side effect of installing 2 or 3 blade adapters is that there are no more PCIe slots available for e.g. USB cards etc.etc...
In other words:
2 adapters: only 1 free PCI slot available and a slow(er) OS...
3 adapters: no free PCI slots available...
Looking at the pictures of the cards (Aliexpress for the first one) they obviously have no PCIe switch, which means they require bifurcation to support more than one blade.Thank you for response I have

If you want to use more than one blade in a single PCIe slot, then you need to spend more than $100 to get a card with a PCIe switch for the Mac Pro or any computer that doesn't support bifurcation.
