1.  AMD BIOS RAID Installation Guide 
 

AMD BIOS RAID Installation Guide is an instruction for you to configure RAID functions by using the onboard 

FastBuild BIOS utility under BIOS environment. After you make a SATA / SATAII / SATA3 driver diskette, press <F2> 

or <Del> to enter BIOS setup to set the option to RAID mode by following the detailed instruction of the “User Manual” 

in our support CD or “Quick Installation Guide”, then you can start to use the onboard RAID Option ROM Utility to 

configure RAID.     

 

 

The term “RAID” stands for “Redundant Array of Independent Disks”, which is a method combining two or more hard 

disk drives into one logical unit. For optimal performance, please install identical drives of the same model and 

capacity when creating a RAID set. 

 

RAID 0 is called data striping that optimizes two identical hard disk drives to read and write data in parallel, interleaved 

stacks. It will improve data access and storage since it will double the data transfer rate of a single disk alone while the 

two hard disks perform the same work as a single drive but at a sustained data transfer rate.   

 

Although RAID 0 function can improve the access performance, it does not provide any fault tolerance. Hot-Plug any HDDs of the 

RAID 0 Disk will cause data damage or data loss. 

 

RAID 1 is called data mirroring that copies and maintains an identical image of data from one drive to a second 

drive. It provides data protection and increases fault tolerance to the entire system since the disk array 

management software will direct all applications to the surviving drive as it contains a complete copy of the data in 

the other drive if one drive fails. 

RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 10 solution for improved performance 

plus resiliency. The controller combines the performance of data striping (RAID 0) and the fault tolerance of disk 

mirroring (RAID 1). Data is striped across multiple drives and duplicated on another set of drives.     

RAID 5 stripes data and distributes parity information across the physical drives along with the data blocks. This 

organization increases performance by accessing multiple physical drives simultaneously for each operation, as well 

as fault tolerance by providing parity data. In the event of a physical drive failure, data can be re-calculated by the
