If anyone is running similar hardware and is able to get better software RAID performance, I would be very interested to hear the parameters.
I've tested some configurations with 128 GiB streams (iozone) on a dual Xeon 2.4GHz 2G RAM machine (running XFS).
3ware HW-RAID1, Linux SW-RAID0: read 263 MiB/s, write 157 MiB/s 3ware HW-RAID5, Linux SW-RAID0: read 243 MiB/s, write 135 MiB/s Linux SW-RAID5: read 225 MiB/s, write 135 MiB/s 3ware HW-RAID10: read 119 MiB/s, write 91 MiB/s

Thanks Peter,
This array is obviously larger than the 4 disc one I have. Unfortunately you do not have the one result I would really like - SW-RAID10.
It would be interesting to see how it compares to 3ware HW-RAID10.
