HP 273914-B21 - Smart Array 6404/256 RAID Controller Technology Brief page 12

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.

Again, the RAID 6 maximum sequential read/write performance test results shown in Figure 5
indicate significant performance gains for the Smart Array P411 over the previous-generation P800
controller.
