    Hi Fella's,

    I am hoping you can help me out. No matter what I do. As soon as I install Intel RST my Samsung PM810 (64gb) mSata SSD speed drops from a healthy
    250 MB/s to a slow 70-120 MB/s.

    Im going insane trying to fix it.

    I would really appreciate any good suggestions of info.

    Thanks in advance

    Would anyone know how I can go about flashing this drive to a Samsung 470 firmware?

    Is RST Control Panel showing the SSD running at 3GB/s or 6GB/s when that happens?

    Have you already tried the LMP fix? I had to do that with my Crucial and OCZ SSD drives to keep them from randomly dropping to SATA2 speeds. See attached zip file.

    If your bios is set to AHCI,benchmark the SSD using Anvil Storage Utilities without installing a version of Intel RST.
    http://www.ssdaddict.com/apps/AnvilBenchmark_RC6.zip

    Windows has an AHCI and Raid built in storage drivers for these.

    You may find you get better scores using the built in storage drivers.

    On Windows 7 it shows as MSAHCI

    On Windows 8,StorAHCI, a Storport miniport, supports serial advanced technology attachment (SATA) advanced host controller interface (AHCI) controllers in Windows, and replaces MSAHCI.
