RAID5 has very poor WRITE performance compared to RAID10, while READ is
nearly the same speed.
If you do not have a "branded" server like HP or IBM, I can recommend
the Areca RAID controllers http://www.areca.com.tw/ their driver is
included in Linux kernel, and they are pretty damn fast. Change the
onboard RAM to 2GB, with the SAS 16 or 24 port controller this is the
way to have fun.
On their website is also benchmarks about different RAID levels, so you
can compare them.
