If their I/O really is significantly better than mine (and I hear that it is often enough that it is quite possibly true... I do know that my I/O does kindof suck) then it's more than just RAID-10. I use raid 10 on all my new servers, too. But, I don't email people who use too much disk I/O. I should do that, really, as I/O is /really hard/ to effectively limit automatically. (yes, yes, IOnice. but it doesn't work very well.)
