  • How do I configure a RAID Set?

  • At least two SATA hard disks or SSDs are required for a RAID array. To ensure optimal performance, it is recommended to use two hard disks or SSDs with the same model and capacity.


    Configuring the BIOS settings

    Turn on your computer and press Delete to enter BIOS Setup. Go to Settings \ IO Ports \ SATA And RST Configuration, make sure SATA Controller(s) is enabled. To create RAID configurations, go to Settings \ IO Ports \ VMD setup menu, set Enable VMD controller to Enabled and set Enable VMD Global Mapping to Disabled. Then depending on the SATA / M.2 connector you use, set the corresponding Map this Root Port under VMD item to Enabled.

    Configuring a RAID Array

    Skip this steps if you do not want to create a RAID array on the SATA controller.

    After the system reboot, enter BIOS Setup again. Then enter the Settings \ IO Ports \ Intel(R) Rapid Storage Technology sub-menu.


    On the Intel Rapid Storage Technology menu, press on Create RAID Volume to enter the Create RAID Volume screen. Enter a volume name with 1~16 letters (letters cannot be special characters) under the Name item and press Enter. Then, select a RAID level. RAID levels supported include RAID 0, RAID 1, RAID 10, and RAID 5 (the selections available depend on the number of the hard drives being installed). Next, use the down arrow key to move to Select Disks.

    Under Select Disks item, select the hard drives to be included in the RAID array. Press the Space key on the hard drives to be selected (selected hard drives are marked with X). Then set the stripe block size. The stripe block size can be set from 4 KB to 128 KB. Once you have selected the stripe block size, set the volume capacity.

    After setting the capacity, move to Create Volume and press Enter to begin.

    After completing, you'll be brought back to the Intel Rapid Storage Technology screen. Under RAID Volumes you can see the new RAID volume. To see more detailed information, press Enter on the volume to check for information on RAID level, stripe block size, array name, and array capacity, etc.
    With the correct BIOS settings, you are ready to install the operating system.

    Installing the RAID Driver and Operating System

    If you want to install an operating system on a RAID volume, you need to install the Intel® RST VMD Controller driver first during the OS installation process. Go to GIGABYTE's website, browse to the motherboard model's web page, download the Intel SATA Preinstall driver file on the Support\Download\SATA RAID/AHCI page, unzip the file and copy the files to your USB thumb drive.

    1. Boot from a Windows installation media, follow the installation until the dialog: Select an installation type:
      Choose custom

    2. The following is the question about the installation drive

    3. Insert the USB thumb drive and then browse to the location of the driver. When a screen as shown below appears, select Intel RST VMD Controller 467F and click Next to load the driver.

    4. Continue the OS installation.
