    Intel Rapid Storage Technology (pre-OS) driver installatio


    My desktop machine is built on Gigabyte GA-Z87-UD3H and Gigabyte provides the latest driver for Intel Rapid Storage Technology (IRST), which I installed after installing the OS. Same goes for my Lenovo Thinkpad-T420. And for both machine, checking the controller device under the IDE ATA/ATAPI Controllers section in Device Manager I see the driver has been updated to the latest version.


    • I set the SATA controller to AHCI from BIOS
    • On the desktop machine I have one WD 2TB BLACK & one WD 3TB Green
    • I don’t use RAID, & no chance of using in near future, but according to Intel IRST improves performance in single disk scenario too.


    Now I have the following questions –

    1. What is the actual purpose of IRST (pre-OS install) driver that doesn’t get served with a post-OS driver that I installed? There must be some difference, otherwise there wouldn’t be a pre-OS version of the driver. Right?
    2. In the pre-OS procedure (loading the drivers at OS-installation time) after successfully completing the OS installation, do I need that post-OS driver? Because after installing from that one I got a quick launch icon that runs the IRST configuration application. Where do get that after installing the pre-OS driver?
    3. As it is “pre-OS”, when I load it at OS-installation time, does it updates anything at BIOS level or anywhere other than HDD? That’s because I’m going to dual boot Windows 7 with Windows 8.1, and after installing Windows 7 when I install Windows 8.1 & load the IRST driver for that, is there any chance of any “overwriting” or OS-incompatibility? In short, is there anything specific to follow while installing the second OS?

    Hi Nero666 and welcome to the forum! I don't like IRST myself especially if not using RAID. The times I've tried it, got nothing but problems. Just because it is put out by Intel doesn't mean it is good. Recommend not installing it.

    Sadly, that really doesn't answer any of the questions I have in my head.

    Just install the driver and not the full software and you'll be fine.

    Personally I find Intel's RST (driver only) is faster than Windows default SATA driver especially with SATA 300/600 speeds and SSD's, the default MS AHCI driver comes from Vista (yes they still use the same old MS AHCI driver dated from 2006 in Windows 8.1).

    The only new default drivers from Windows 8.1 with Update 1 I find on my system is the USB 3.0 driver it's dated from 2014 which means Update 1 updated the default USB 3.0 driver from Windows 8.1/8.

    IRST drivers is needed by your motherboard's Intel SATA controllers for AHCI features like NCQ to increase system performance and stability.

    How do you install the Intel Rapid Storage technology driver only? There is no option to install the driver only in the software, and I am annoyed that there is an app attached to it that uses resources and I would like to get rid of it as it seems useless (If I don't know about something (like some secret advantages of having the app compared to driver only) please tell, but I am not using RAID, I just have this on a single drive with AHCI enabled). Please provide some information on this, as I haven't found anything yet on the internet.

    Very sorry for bumping such an old thread but I have the very same question as EShirou. I want to install RST but without the software UI. I know it has to be done through the Device Manager but when donwloading the RST zip file, there are 2 INF files and I don't know which one to choose from.

    Any ideas on this?
