Slow NVME gen 4 drive

    I have a 500gb Sabrent 4 drive in a B550 motherboard.

    It is quite slow though, feels like a hard drive sometimes.

    Samsung magician is reporting:

    Read: 946mb
    Write: 576mb
    Random Read IOPS: 43945
    Random write IOPS: 35156


    it used to be 3.4gb/2.5gb a secon with 380k IOPS. What could be wrong? appreciate the help.

    Try using CrystalDiskInfo to check the drive health.

    Might need to be replaced, is it still under warranty?

    Do you have a proper heat spreader or sink on it or is it just the stick?

    I would presume it is still under warranty as very new.

    It is just the stick that is the NVME though it is under the "heatspreader" that came with the motherboard that it is screws under. temperature seems to be 41c. is this high?

    It's unlikely to be a drive health issue.

    How many other drives and pcie devices have you got connected to it.

    Maybe the speed got turned down somehow.

    What CPU and Chipset is it, and what other PCIe devices are installed?

    CM does say it's running in PCIex4 4.0 tranfer mode

    41c is fine but monitor it for a file transfer test. Eg. Move a large file on/off it and see if it thermal throttles.

    Might be an obvious question but worth asking anyway. Is the plastic film from under the heat spreader removed?

    Also, aren't there some B550 where you won't get Gen 4 speeds depending on what slot you use? The B550 Tomahawk springs to mind.
    What one are you using?

    I have a western digital on the other slot (gen 3 speed slot). I also have 2x SSD. (Details in original snapshot from crystal mark).

    I moved a 5gb file back and across twice didn't seem to affect the temp.


    The drive is quite full (75gb left of 465gb). Could this cause problems?

    weird, running it again

    SmJ6OYC.png


    I guess the thing here is that it feels noticeably slow. I don't care about benchmarks. For example sometimes when I click on desktop it will actually "load" the desktop which takes a second or two. That kind of slowness. Bizaare. On my 960 Pro drive it was always instantaneous even if the "stats" were not close.

    Every B550 board has this caveat: the chipset has only PCIe gen 3 capability, but the slot close to the CPU can benefit from PCIe gen 4 from the CPU. Same goes for the GPU slots: the top one, close to the CPU, can run PCIe gen 4, but not the others, which are connected to the chipset, and run at PCIe gen 3 speeds.

    I find the information easy to read on ASUS specs. Here's an example.

    Expansion Slots section details how there is one PCIe 4.0 slot provided by the 3rd gen CPU, and additional PCIe 3.0 slots provided by the Chipset.

    Same goes for storage. One m.2 slot runs at PCIe 4.0 provided by the 3rd gen CPU, and the other is PCIe 3.0 compatible, provided by the Chipset.

    OP, I wonder if you have maybe added a new GPU or other drives to your system, and that is what caused the drop in speed. As you know there's a limited number of PCIe lanes, and these are shared across your devices.

    Maybe you could run a test while having one or both of the SATA drives disconnected. That would be simpler than removing the other m.2 drive.

    Thank you I did not consider this. I have run the samsung benchmarks a few times as concerned about heat. (the gen 4 drive sits under this heatsink thing, right underneath the graphics card (2060 super). It seems to sit at 40c at default and goes up to 46c when its benchmarked a few times. Is this too high?


    I did not know there was a limit on PCI lanes I am not a computer expert. I will remove some hard drives to see if that helps. But I am still surprised and concerned that this would make a 5gb a second drive feel so laggy on normal usage.

    What are you are describing is really nothing to do with pcie 3.0/4.0 or anything like that, or not having enough space on your HDD.

    You are entirely correct, there is no reason it sound be so abnormally slow as to feel like an ancient mechanical hard drive, even if it were mildly starved of bandwidth it still would not behave anywhere near that poorly.

    Just sounds like a faulty drive most likely.
