[. . . ] Reads and writes sector of data interleaved between multiple drives. When any disk member fails, it affects the entire array. Performance is better than a single drive since the workload is balanced between the array members. This array type is for high performance systems. Identical drives are recommended for performance as well as data storage efficiency. The disk array data capacity is equal to the number of members times the smallest member capacity. For example, one 40GB and one 60GB drives will form an 80GB (40GBx2) disk array.

This is the slowest form of fault tolerance because the data has to be replicated onto two disks at the same time. However, this is the simplest way to provide high reliability. If one of the mirrored drives suffers a mechanical failure or does not respond, the remaining drive will continue to serve and provide correct data. If one drive has a physical sector error, the mirrored drive will continue to function. Due to redundancy, the drive capacity of the array is half the total drive capacity. For example, two 40GB drives that have a combined capacity of 80GB would have 40GB of usable storage. With drives of different capacities, there may be unused capacity on the larger drive. RAID 1 increases cost as it takes twice as much hard drives to build our arrays.

You may use RAID BIOS Setting Utility provided by VIA to setup your disk array. R A I D BI O S S e t t i n g Ut i l i t y In order to make sure your system can recognize and operate Serial ATA RAID device smoothly, we have to enter RAID BIOS Setting Utility to do some configuration. After finishing the BIOS setup and reboot, you will see [Press <Tab> into User Window] about half way through the boot up. When you enter, you will be presented with a screen as shown below. You can use this utility to create or delete your disk arrays. 68 AK86-L / AK86-N Online Manual P H O E N I X- AW A RD B I O S System parameters can be modified by going into BIOSU Setup menu, this menu allows you to configure the system parameters HT U TH and save the configuration into the 128 bytes CMOS area, (normally in the RTC chip or in the main chipset). The Phoenix-Award BIOSTM that installed in the Flash ROMU of the motherboard is a custom version of an industry standard HTU TH BIOS. The BIOS provides critical low-level support for standard devices such as hard disk drives, serial and parallel ports.
