Chapter 1. Introducing the 3ware® 9000 Series Controller Available RAID Configurations The following RAID levels and configurations are available for drives attached to a 3ware RAID controller: • RAID 0 • RAID 1 • RAID 5 • RAID 10 • RAID 50 • Single Disk • JBOD • Hot Spare RAID 0 Provides striping, - 3Ware 9550SXU-8LP | User Guide - Page 17
by preserving the data on one drive if the other drive fails. Fault tolerance is a basic requirement for mission critical systems like web and database servers. 3ware uses a patented technology, TwinStor®, on RAID 1 arrays for improved performance during sequential read operations. With TwinStor - 3Ware 9550SXU-8LP | User Guide - Page 18

Requires a minimum of six drives. Several combinations are available with RAID 50. For example, on a 12-port controller, you can - 3Ware 9550SXU-8LP | User Guide - Page 19
