4-1-3 Serial ATA BIOS Setting Utility Introduction RAID Levels RAID (Redundant Array of Independent Disks) is a method of combining two hard disk drives into one logical unit. The advantage of an Array is to provide better performance or data fault tolerance. Fault tolerance is achieved through data redundant operation, where if one drives fails, a mirrored copy of the data can be found on another drive.

6) Complete RAID utility installation. More information on steps 4 and 5 is provided. (For more detailed setup information, please visit "Support\ Motherboard\ Technology Guide section" on our website at http:\\www.gigabyte.com.tw to read or download the information you need.) Configuring the NVIDIA RAID BIOS The NVIDIA RAID BIOS setup lets you choose the RAID array type and which hard drives you want to make part of the array.
