New SSD giving bad performance

Hello, I just bought a 850 Evo SSD from Samsun last week, but it is giving bad performance, specially in DQ Read / Write / Mixed, see image below, on the right:



I think it must have something to do with some configuration parameter, but I am new to SSD and have no idea :/

  1. The easiest thing to do is install the software that came with your SSD. The software is calles Samsung Magician. Once installed run the application. On the left menu go to System Management->OS Optimization and you can choose one of the TABS that suit best for your needs. I have Samsung 850 PRO and I chose advanced tab and have the following settings and my SSD runs superb!! Also make sure on your BIOS AHCI is enabled! I can suggest trying these options and see if the bad performance persists.

    Hibernation Mode-> Deactivated
    Virtual Memory-> Default
    Indexing Service-> Activated
    Prefetch/Superfetch-> Deactivated
    Write Cache Buffer-> Activated
    Write Cache Buffer Flushing-> Activated
    Power Options-> Maximum Performance
    System Restore-> Default
  2. Also be sure to enable RAPID mode (in Samsung Magician) to give you the best performance.

    Hello Sybnios, thank you for your answer.

    I do have Samsung Magician installed and AHCI enabled.
    I have tried different settings with the OS Optimization but none solved the issue :(
  4. First ,you should set your SATA controller mode to AHCI. IF you don't know how to do it, read your motherboard manual carefully. AHCI WILL enable many features like : Trubo write. you may need to install a new windows (unless you you know how to edit your registry manually with the right way),then you should install Samsung Magician.

    Thats odd.. Have you checked if the TRIM is enabled? You can check that through command prompt:

    1.Open Command Line Prompt.
    2.Type "fsutil behavior query DisableDeleteNotify".
    3.If the result is 0, then it means that TRIM is enabled. On the other hand, if the result is 1, then TRIM is disabled.

    Also make sure automatic disk defragment is disabled! That won't be the issue for your problem but its in the list for the best SSD optimization

    I can't think of anything else at the moment. :( If I find anything I'll post it.

    Thanks again for your answer Sybnios,

    I tested the TRIM feature and it returned 0.
