Create Disk Array Display, RAID 5 Example Select RAID configuration The Escalade ATA RAID Controller gives you a choice of four RAID configurations. Select one. ■ Stripe (RAID 0): maximizes performance and capacity through a process called striping. High performance arrays write portions of a single file across multiple drives. There is no fault tolerance. ■ Mirror (RAID 1): duplicates or "mirrors" the data on both drives. No data will be lost if one of the drives fails. Note that a RAID 1 cannot be used to make a backup copy of an existing drive. Creating a RAID 1 erases all data on both disks. www.3ware.com 33
