Acer Aspire 9800 Intel Matrix RAID User's Guide - Page 2

English RAID 0 is useful for increasing performance for systems in which there is a high amount of disk usage, such as those involved in intensive database work. It is also a popular choice for gaming systems where performance is desired. However, since data is shared between drives without redundancy, hard drives cannot be swapped out as all disks are dependent upon each other. RAID 1 RAID 1 creates an exact copy (or mirror) of a set of data on two or more disks. The array can only be as big as the smallest member disk, however. A classic RAID 1 mirrored pair contains two disks, which increases reliability by a factor of two over a single disk, but it is possible to have many more than two copies. Since each member can be addressed independently if the other fails, reliability is a linear multiple of the number of members. Intel Matrix RAID Intel Matrix RAID utilizes two physical hard disk drives. It assigns part of each disk to a RAID 0 array, and the other part to a RAID 1 array, allowing users to enjoy the advantages of both RAID levels. Matrix RAID provides users with a safe area (RAID 1) for documents and other important data that must be protected, as well as a faster area (RAID 0) for the operating system and other applications.
