    Slow SSD speeds with Intel 520 series 240GB

    Hi all,

    I'm using Win10 x64 and Intel 520 240GB SSD:

    For my mobo, Asus P8Z77-V-Deluxe, I downloaded the official asus chipset drivers.
    There is one for Win8.1 x64 and a Beta version for Win10.

    The chipset driver for Win8.1 has installed the following:
    1. under Device Manager> IDE ATA/ATAPI controller > Inter 7 series/C216 chipset Family SATA AHCI Controller
    2. Version - Date 2013/08/01

    If I install the Asus Win10 chipset driver, then instead of the Inel SATA controller, I'll end up having Standard SATA controller by Microsoft.

    I'm currently using the Asus beta Win10 chipset driver, however I manually installed the Intel SATA controller which is officially supported on Win8.1 and is digitally signed.

    I ran two SSD benchmark test with AS SSD (latest version).

    With just the official Win8.1 chipset driver as mentioned above, I'm getting the following results:

    Sorry, but your speeds are within the margin of error. You cannot get exact results no matter how many times you run the same benchmark. You'll never get close to what Intel lists.

    I'm not looking to get Intel results. It should be Just like the last screenshot because I used to get the exact results with slight variations, unlike my current benchmarks
