    I just bought a Samsung 950 Pro 256Gb m.2 drive and my performance numbers are no where close to where they should be *I THINK*.. Can someone please tell me what im doing wrong here. I have the NVME samsung driver installed, along with other updated drivers for this JUST FRESH win10 install on this NVME m.2 drive. I took a snap shot of my settings and AS-SSD benchmark results and numbers appear to be way short.... HELP!@!!!!

    Hi there

    Can you try check those speeds with Samsung Magician and try to test that with one GPU,just to be sure ?

    Thanks,Jura

    1. How much space is being used on this drive?
    Reviews test a blank drive.
    2. What intel RST/nvme driver are you using?
    Here is latest nvme driver
    NVME

    You are thinking not enough pcie lanes? That cant be right.

    the drive *JUST* has the OS on it and nothing else.. free space on drive = 210gb's..... I have the samsung nvme driver installed, why do i need an intel nvme driver? Am i missing something? Something isnt "Right" here... my older SM951 256gb ahci drive had reads over 2000mb's, surely nvme can achieve the same if not more on equal capacity drives..... :3eyes:

    Yes and no there,in one sense I think this can be down to PCI_E lanes and in second this can be as PCI_E lanes are shared like with SATA(in his case I think SSATA3_2) and GPU

    But I'm not 100% not sure if I'm correct with that,but it easy to at least test that in his case

    Thanks,Jura

    The performance also depends on the enrgy settings in Windows. Please check if high performance is enabled and if you use PCIe energy saving features (in UEFI).

    Your write times are up to spec it is just the read times that are down, I am sure you have but did you run AS SSD a few times mine will give different numbers every time ,just a thought with those two 980s have you got enough PCI-E lanes? it is just i read some where about that
