DATA RATE (MB Per Second) The performance gains shown by the Smart Array P411 in RAID 5 and 6 sequential writes (Figures 4 and 5) result from improvements to the Smart Array firmware and hardware. The RAID 5 maximum sequential read/write performance test results shown in Figure 4 indicate significant performance gains for the Smart Array P411 over the previous generation P800 controller.
