I think the best place to pose the question would be at [email protected] where you can find Neil Brown, and other md developers - you'll need to include your kernel version, and any other tuning you've done at the block layer, or with the PERC and it's driver. I have had sequential reads at 800M per second with md before, with (I think) 8 2TB 7k drives, but I don't think I've benchmarked sequential writes on a comparable system.
