Chapter 3 3-1 Appendix Configuring a RAID Set RAID Levels Minimum Number of Hard Drives Array Capacity Fault Tolerance RAID 0 RAID 1 RAID 10 ≥2 2 4 Number of hard drives * Size of the smallest drive No Size of the smallest drive (Number of hard drives/2) * Size of the smallest drive Yes Yes Before you begin, please prepare the following items: •• At least two SATA hard drives or SSDs.
Install the RAID driver and operating system With the correct BIOS settings, you are ready to install the operating system. Installing the Operating System As some operating systems already include RAID driver, you do not need to install separate RAID driver during the Windows installation process. After the operating system is installed, we recommend that you install all required drivers from the motherboard driver disc using "Xpress Install" to ensure system performance and compatibility.
3-2 Drivers Installation •• Before installing the drivers, first install the operating system. •• After installing the operating system, insert the motherboard driver disc into your optical drive. Click on the message "Tap to choose what happens with this disc" on the top-right corner of the screen and select "Run Run.exe." (Or go to My Computer, double-click the optical drive and execute the Run.exe program.
