Will this motherboard fully support the Read, Write, etc of a Samsung 950 PRO M.2?

Ferrariassassin · May 17, 2016

My motherboard and M.2 SSD is below and was wondering if my motherboard was allowing my M.2 Samsung 950 PRO to run at its full potential. On my Motherboards site it says its M.2 is

M.2 for SSDs drives with up to 10 Gb/s data transfer

But i have no idea what that means lol. The Samsung 950 PRO has

Max Sequential Read/Up to 2200 MBps

Max Sequential Write/Up to 900 MBps

4KB Random Read/Up to 270,000 IOPS (4KB, QD32)/Up to 11,000 IOPS (4KB, QD1)

4KB Random Write/Up to 85,000 IOPS (4KB, QD32)/Up to 43,000 IOPS (4KB, QD1)

MTBF/1,500,000 hours

And i do not know how to compare that to my Motherboards 10 Gb/s data transfer nor if it fully supports it so i hope someone can help because i have no idea.

Yes. The system wouldn't allow the use of a drive that was incompatible with the pipeline. 10Gb/s is equal to 10,000 MBps, so it can handle far more than what is being required by the drive. The onboard standard for M.2 is overly capable of supporting the current speeds of the available M.2 drives on the market, and then some.

The more important question would be whether or not enough PCI lanes were available. If you had all of the lanes saturated by using several PCIe slots, SATA drive headers and M.2, you could run into issues with not enough PCI lanes. Usually that's not the case though unless you're running SLI or Crossfire configurations.

If it doesn't, what are you going to do?

SO just trust in the design, stick it in there and use Samsung Magician to benchmark it.

Further, the specs for your board states:

(M.2, SATA Express, and SATA3 4/5 connectors can only be used one at a time. The SATA3 4/5 connectors will become unavailable when an M.2 SSD is installed.)

So there are contributing population rules to be aware of as well.

Oh i am already using the Samsung 950 PRO on my motherboard. I was just wondering if i was running it to its full potential because if not ill send it back and just use my Samsung 850 PRO. And ok ill do that.

But i thought M.2 was different speeds depending on the motherboard? I will be buying two 1080 when they come out but may stick to one because i may not have enough lanes. As of now i use 1 for my 980Ti and Samsung 950 PRO and idk if ram or CPU uses a lane or not.

Actually, you don't use "1" for your 980 TI. You use 16 lanes. That's why they are called x16 slots. When you use them in SLI or Crossfire, most often both cards drop to x8 speeds or in some cases, only the second card is dropped to x8 speeds while the first card uses x16. Some boards don't even support multi card configurations at all and others support only limited speeds at x4 on the second card, making it useless for SLI or Crossfire, but ok if the second card is to be used independently just for display purposes.

It all depends on the platform and motherboard chipset. In your case, you can't do that anyway since that board does not support SLI and only supports x16 + x4 crossfire.

You will not be able to use two 1080's on that board. So you have plenty of lanes currently available so long as you understand that the M.2 slot, when in use, disables the SATA 4 and 5 headers. The other SATA headers are unaffected.

I am so sorry but this is so confusing to me

I understand most things when coming to PC and such but when it comes to Lanes and Data speeds i go full retard mode. I see that my CPU only supports 16 lanes and my 980Ti uses 16 so does that mean if i use my Samsung 950 PRO it will not work because it needs 4 PCIe slots and my GPU is using all 16 of my PCIe lanes. I will upgrade to one 1080 but it will be like 5 months from now or ill wait for the best Pascal card to come out like the 1080Ti or whatever it will be called but thats later on so its not important right now. Also is M.2 the same as a PCIe 16 in terms of speed?

Darkbreeze · May 17, 2016

Actually, the Samsung 950 Pro is much faster than any of the current PCIe storage solutions. Less expensive too than any of them that are even remotely in the same ballpark when it comes to speeds. The 16 lanes used by your card shouldn't affect the M.2 device. It's rather complex sorting out the lane usage on a given chipset, but you should be ok.

You can't use an SLI configuration anyhow, so you'll have plenty of lanes.

Ok thanks man! So in the end, my Samsung 950 Pro will still perform better than my Samsung 850 PRO? I was worried that the 950 would be bottlenecked to the same speed as the 850 so phew thats good to hear.

Darkbreeze · May 17, 2016

No, they use entirely different, but codependent, portions of the chipset.
