Hello,
 
So, first post, and pretty much amateur builder here.  Feel free to tell me I'm an idiot/moron/fool, though I do better with constructive criticism.  I'm here to learn.
 
I pulled a Samsung SM951 (512GB) M.2 SSD out of a laptop and tossed it into my desktop build, only to find the speed to be about 1,000MB/s slower than it was in the laptop.  Is this the expected/normal speed for the M.2 SSD drive in the X99 Classified?  I have also tested two Samsung 950 Pro M.2 SSD (512GB) in the M.2 slot in my X99 Classified only to find them returning about the same speeds as the SM951.  I was expecting more like 2500 MB/s like I get from the M.2 slots in my laptop, instead of the 1600 MB/s speeds I'm seeing.  If these aren't normal speeds, any suggestions on what I can do to speed it up?  Or like I said at the beginning of the post, feel free to tell me I'm a retard.  Would it help to move the second GPU?
 
I have included a screenshot of the SM951 test and I think the pertinent shot of BIOS.
 
Other info:
BIOS 2.02
i7-5960x
Titan X - x2 SLI
Samsung 850 Pro 1TB boot drive
 
Think that's it?

The M.2 socket on the X99 Classified is seviced via the PCH with 4 lanes Gen 2 PCI Express. Therefore your M.2 speeds will not be as fast as 4 lanes Gen 3 PCI Express.

Exactly.   You could put a PCIe 3.0 M.2 bracket in one of the unoccupied PCIe 3.0 slots and get them 3.0 speeds that way but as it stands, the M.2 onboard the X99 Classified is unfortunately 2.0.

Thanks for the quick replies guys!  I was wondering if this was the case.

Can someone recommend a good m.2 ssd for my x99 classified? would a Samsung 950 PRO NVMe M.2 512GB be a good option?

 
A 950 Pro or a intel 750.  I think the 950 is a bit faster in certain areas.  
 
Just make sure you use the PCIe Slots and NOT the M.2 interface because its capped at PCIe 2.0 speeds which is slower then 3.0, which you would get at least on the PCIe slots.  Just have to purchase a M.2 to PCIe adapter, depending if you go with 950 Pro because the intel 750 is already set on one.

Anyone know if an ASUS Hyper M.2 x16 adapter card will work in the X99 Classified?

I don't see an issue with that, assuming you're using it for PCIe 3.0.
