So ive received my 950 pro and seem to be getting under par performance in win10. I'd like to verify with anyone else that may have the same drive as mine. 
 
I've also included a bench from my sandisk 960gb ssd which destroys this m.2 Samsung 950 pro as reference.
 
 
 

I have done the same bench on both 1.01 and 1.02... same results. The other ssd's I have on sata ports both perform as they should which is comparable to other online benches however the 950 on m.2 through pci-e 4x is not functioning as it should.
 
However I have come across a thread here on this forum that shows a SM951 with micro2 running at its normal potential.  The owners nick is david_etches.

So before I pass judgement to say that my 950 is defective, I'd like to know who else may have 1 and what their performance is? Mine is a 256gb version just a FYI.
 
Thanks

I get the same result with the 950 512gb using AS-SSD but Samsung Magician benchmark seems to be showing me the expected results.
Also tried ATTO and those results are closer to Magician than AS-SSD so maybe there's a problem with AS-SSD and nvme (with whatever controller the 950 uses)?
 
EDIT: Also using the 1.02 bios on Win10

AS SSD is not famous as accurate software.
CORSAIR ask from customer to use ATTO and ignore AS SSD for their SATA III SSD.
And Samsung probably recommend some software.
I think your results are fine...
You can compare over net with results and try some other software...

Samsung will make huge profit with this and other M.2 drives and brands who continue to sell SATA III SSD will make less and less profit from expensive devices because their speed will be completely in shadow of M.2 drives...
Example CORSAIR Neutron XT 480GB cost 335$...That's same as Samsung 950 PRO 512GB.
Speed is five time faster.
No doubt companies will continue to sell SATA III SSD in next years but more as devices for games and bigger models, 960GB, 1TB. 
People will not look any more who is faster CORSAIR or Intel SATA III as before. Their limit is reached before 3 years and in mean time every company launch several models advertised as faster and better. Finally now is over. SSD is necessary.
But M.2 for OS and important software, 1-2 SATA III SSD for games, 1TB Size and HDD for storage and keep backup files on safe mostly 2 and 3TB.
I afraid price will not go down much because no matter on speed people need them and that's enough for brands who produce to ask regular price.

Also add that CrystalDiskMark shows poor results with this mobo, HDTune as well.

I went and returned this 950 pro infavor of the 850 Pro. On paper the 950 pro is nice along with some synthetic benches but in any realworld application, I just dont see any difference even compared to my existing 830 samsung.

Did you compare 950 PRO with results over net?
Some tests didn't work well with some previous SSD SATA III.
You should ask manufacturer what to use...
It's very small chance that your 950 PRO not work good.
My SSD in many tests didn't show results as CORSAIR sad not only mine and other people,
but they ask testing with ATTO because they use ATTO.
And in ATTO he show real speed.
 
You should know that you will not see difference compare with SATA III SSD except when computer work something.
But price of 512GB M.2 950 PRO is same as 480 CORSAIR Neutron XT. And I think price is OK.
Many thing depend of controller and of software version. That's new device wait little and check performance on net.
 
Edit: I know checked on Samsung site, some results are OK, but some not...
I looked Samsung Magician.
M.2 slot on EVGA X99 Micro 2 is transfer speed up to 32Gb/s???
On ASUS X99M-WS is up to 10Gb/s because of that I stop instantly to look other specification of that board.

And you suspect on Mobo (Micro 2) or (950 PRO)M.2 or problem with software/OS installation?
Did you check maybe how Samsung 950 PRO behave on high temps, maybe some throttling, losing speed,...

OblivionLord
It's not throttling due to high temps. Samsung Magician is showing comparable results with other online testers with other mobos and it is showing a high 2k sequential speed for read along with 1k for seq for write. There certainly is no throttling happening. Only way to find out for sure what the issue is if it someone else can test the 950 pro on 1.02 bios with this mobo. SM951 works fine with every bench out there, but 950 pro is having problems.

My guess would be either the BIOS needs an update for the 950 Pro or the SSD is faulty.

Did you guys try to enable a special M.2 compatibility option in bios intoduced in recent EVGA bios update and compare results with 950 Pro? It should limit RAM speeds to 2800Mhz and BCLK overclock, but i don't think this board likes BCLK OC and 2800Mhz Ram anyways)

I have already mentioned in another thread that I have a new Micro2 running BIOS 1.02 with the 256GB 950 Pro and getting 2200MB/Sec Reads and a little over 1K Writes as advertised in Magician4. GTXJackbauer suggested to tack this drive onto an add-in card/adapter and stick in to a PCIe 3.0 slot and get faster thru-put. Is this a valid suggestion? Would you get 32GB/Sec vs the 10GB/sec that Magician4 states is the limit for the drive?

I've only suggested those that have the first line of X99 Micro and X99 Classified since the M.2 interface on the MBs are PCIe 2.0 instead of the 3.0 the Micro2 has and to only get the 3.0 advertised speeds on those 2.0 boards was to grab an adapter to get the 3.0 from the actual slots.  
 
As I had posted earlier, it either needs a BIOS update or its a faulty SSD.  It could be a faulty SSD if the BIOS is up to date.

My drive reached 78-degree celsius running CrystalDiskMark at an ambient temp of 20. I've AIDA64 to monitor my temps.

That is some impressive figures. That must be one fast PC.

Hi drppower,
 
Are you operating Windows 7 or 10 and booting up from the 950 pro ?

Thank you
