[. . . ] 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. 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.

It takes a Disk stripe using two disks, and mirrors it to another set of disks for fault tolerance. Data is stripped across several disks, each disk has partner with exactly the same data on it. You get the benefits of fast data access as in RAID 0, with the fault tolerance of RAID 1. You need double the number of disks as a RAID 0, half for each side of the mirror. There are other RAID configurations in addition to those described here, but these are the types most commonly used in the industry.

Although it doesn't provide data integrity advantages as RAID levels 0 and 1 have, it can be very helpful for users dealing with extremely large file sizes such as animation or digital editing files.

The Phoenix-Award BIOSTM that installed in the Flash ROM of the motherboard is a custom version of an industry standard BIOS. The BIOS provides critical low-level support for standard devices such as hard disk drives, serial and parallel ports. AOpen's R&D engineering team had optimized most BIOS setting of this motherboard. But, the default setting of BIOS still can't fine-tune the chipset controlling entire system. Hence, the rest of this chapter is intended to guide you through the process of configuring your system using setup.
