Saw this on LKML yesterday, thought it might be relevant. "Hardware vs. Software Raid Speed" http://marc.theaimsgroup.com/?l=linux-kernel&m=115631607926848&w=2 Jeff Garzik's response http://marc.theaimsgroup.com/?l=linux-kernel&m=115639048429335&w=2 Pretty much, unless you have a really really expensive high end RAID controller (which our consumer motherboards dont), it'd be better for you to use software raid. Some consumer motherboards pretend to do hardware raid, but really, it's just software raid in the windows driver, a fancy boot splash, and some magic in the bootloader to get windows booted.
