    Samsung 970 Plus Drive Slow in W10 But Proper Speed in SAFEMODE

    Good day,

    Apologies for posting about non ASUS laptop but I have always gotten knowledgeable replies here and the problem is a storage issue. Thank you.

    I have Alienware R4 17 laptop and just upgraded to NVME Samsung 970 Plus. Speeds from CrystalDiskMark 6 are 2300Mb/s vs expected 3500Mb/s in NORMAL Windows environment. All Read/Write speeds are proportionately slow.

    When I run CrystalDiskMark 6 in SAFEMODE I observe expected speed of 3500Mb/s. I conclude that something is interfering with ssd speed while in Windows. Whatever it is, is DISABLED when booting to SAFEMODE.

    Question is HOW do I find the offending software or driver and get expected speed of 3500Mb/s in normal environment of Windows 10?

    Thanks

    Make sure you load the NVME driver from Samsung for the SSD device. It is not out of the box in windows. That should fix it.

    You need to check temperatures. If temps reach over 80C performance will drop instantly.
    NVMe M.2 need heatsink to be installed or simply performance will start good and than suddenly on half benchmark you will see unreal drop and in AIDA64 you will see that temp is over 81-83C.

    It's very hard that Samsung SSD M.2 NVme and SATA III SSD not reach performance advertised.
    Maybe 5% worse. Because they test on huge machine many of them in same time and see if someone is not good.
    Same as RAM.

    But if advertised speed is 3500/3000 and you can't reach 3000/2500 and that's confirmed and in service they will replace you SSD.
    My Samsung 850 EVO 1TB after 2 years is still great, on 99% of quality and still reach exactly same performance as advertised.
