I have a X99 Classified and I'm looking at the new M.2 drives from Samsung.
http://www.samsung.com/us/computing/memory-storage/solid-state-drives/ssd-960-pro-m-2-512gb-mz-v6p512bw/
 
Are they compatible with my motherboard?

I\m using an Sm961 on an X99 Micro 2 with no problems.

You'll want to grab a PCIe adapter for any M.2 SSD PCIe 3.0 x4 since the M.2 interface on the X99 Classifieds is unfortunately only PCIe 2.0 x4.

If this m.2 drive is for pleasure (gaming) and not an IOPS intensive database server you will see no difference if you use the onboard m.2 or a PCIE 3.0 adapter - http://forums.evga.com/EV...ad-Times-m2556132.aspx
 
And if someone doesn't believe the work that I and other reviewers have done, then I challenge you to do the work and show us the results.

Fisticuffs, Sir!

Challenge in what form: pistols, rapiers or something in between? :D

 

Any new updates from the OP???

Haven't bought anything yet. It might be a nice Christmas gift to myself.
 
Probably getting a 950 Pro.

 
If you do get the 960 Pro M.2 Drive, and it works on your X99 Classified please post your success. I did not have success with this chip, and have since returned it. Yes, you may have better luck with the 950.  I'm guessing there needs to be another BIOS update for the Classy Board and/or a Samsung Magician update for this (960 Pro) chip to be compatible with the Classy board.
I've been waiting and watching the boards for one successful install of the 960 Pro M.2 SSD on the X99 Classified. Still waiting....

I too have version 2.03 installed. Yes, here are my 2 threads I opened on this exact topic.....

I tried the driver, says no SSD on system to install driver to.

Just installed my 960pro 1tb M.2 last night in my x99 FTW K and its Awesome :)

I have a XP941 installed on my Classified's M.2.

Guys I just installed a 960 evo M.2

MZ-V6E500 (500 GB) on the onboard M.2 slot on my x99 classified

 
So far it is working great! 
 
Installed windows on it in like 3 minutes
 
boots into windows in like 1 second (after getting past the bios screen)

Awesome, was waiting for somebody to have success with this drive on the Classy MoBo! Glad to hear it! Although I tried the 960 Pro. Don't think there would be a difference in compatibilities.
Now, if you don't mind. What did you have to enable and disable in BIOS? Did Windows recognize the drive right away? Are you using Samsung Magician 5.0? Does your drive show up in BIOS as PCIe 3 X 4?
 
Any info would be helpful. I've since returned the 960 Pro M.2 drive. I wasn't sure if it was a compatibility issue, or the drive was defective. Beginning to believe the latter. So this may be encouraging news. Maybe be looking to try again and purchase a new drive.

You already took a look at this guide? http://forums.evga.com/X99-M2-Getting-it-to-work-STEP-BY-STEP-m2476830.aspx 

 

Also here is a benchmark result

There's almost twice the difference in M.2 PCIe 2.0 to 3.0.  You can use the PCIe slots with a M.2 adapter to get the SSD @ 3.0 x4 speeds otherwise you're stuck with 2.0 x4 on the MB's M.2 interface.  Speeds will depend on which drive you get.  The fastest M.2 SSD is the 960 PRO PCIe 3.0 x4.  
 
Here's an example of a benchmarked Samsung 960 Pro M.2 NVMe SSD (2TB).

yeah looks like GTXJackBauer is right about PCIE 2.0 vs 3.0 speeds
 

Summary of PCI Express Interface Parameters:

• Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
• Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
• Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
• Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s

 

 
And it looks like the onboard m.2 slot is pcie 2.0 only since is uses the PE5 interface on the motherboard. See below:
 
PCI-E Slot Breakdown PCI-E Lane Distribution (40 Lane Processor)

 
PE1 – x16 (x8 if PE2 is used)

PE2 – x8

PE3 – x8

PE4 – x16 (x8 if PE3 is used)

PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH)

PE6 – x8
 
PCI-E Lane Distribution (28 Lane Processor)

PE1 – x16 (x8 if PE2)

PE2 – x8

PE3 – x8 (Slot is *NOT* functional with a 28 lane processor.)

PE4 – x8

PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH)

PE6 – x4
 

 
 
I am going to try putting my evo 960 m.2 in a pcie adapter card and see if I can get PCIE 3.0 going. If I get it working I will provide benchmarks.
