RAID 5 Configuration Example R5 FusionTM Technology significantly improves RAID 5 write performance 3ware's R5 Fusion significantly improves RAID 5 write performance for both large sequential and small random transactions. This advanced block caching firmware technology is combined with StorSwitch to deliver extremely high performance for RAID 5 write operations. This performance improvement is applicable to only the first RAID 5 array on the RAID controller. Additional RAID 5 arrays on the RAID controller will not benefit from the R5 Fusion technology. Note: R5 Fusion is available only with Escalade 7500 and 8500 ATA RAID Controllers. 24 www.3ware.com
