    Good day,

    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

    Do you have the samsung NVMe drivers?

    You can disable individual apps from starting with windows by opening Task Manager and then going to the startup tab. I'd disable them all and test it to see if it is indeed one of those apps. Then you can enable them a couple at a time and retest.

    Hi,

    Do you have the samsung NVMe drivers? YES

    You can disable individual apps from starting with windows by opening Task Manager DONE already... NO CHANGE.

    Then it's not a normal startup application causing the issue.

    Was this a fresh install or did you clone the drive?

    I mean if you're concerned about maximum performance then I would do a fresh install of windows. If that's too much work then I would just be happy you still have a fast drive and that you'd never notice the difference in speeds anyway.
