Appendix A: Understanding RAID ● 48 RAID Technology Overview RAID is the technology of grouping several physical drives in a computer into an array that you can define as one or more logical drives. Each logical drive appears to the operating system as a single drive. This grouping technique greatly enhances logical-drive capacity and performance beyond the physical limitations of a single physical drive.
Appendix A: Understanding RAID ● 49 When selecting a RAID level for your system, consider the following factors.
Appendix A: Understanding RAID ● 50 RAID 1 Arrays A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays provide improved performance, with twice the read rate and an equal write rate of single disks. However, capacity is only 50 percent of independent disk drives.
