Want to get an idea of what speed advantage adding an expensive hardware RAID card to your new server is likely to give you? You can benchmark the performance difference between running a RAID using the Linux kernel software RAID and a hardware RAID card. My own tests of the two alternatives yielded some interesting results. In testing both software and hardware RAID performance I employed six 750GB Samsung SATA drives in three RAID configurations -- 5, 6, and 10. I measured performance using both Bonnie++ and IOzone benchmarks. I ran the benchmarks using various chunk sizes to see if that had an effect on either hardware or software configurations.
