RAID5 has very poor WRITE performance compared to RAID10, while READ is=20
nearly the same speed.

If you do not have a "branded" server like HP or IBM, I can recommend=20
the Areca RAID controllers http://www.areca.com.tw/
their driver is=20
included in Linux kernel, and they are pretty damn fast. Change the=20
onboard RAM to 2GB, with the SAS 16 or 24 ****t controller this is the=20
way to have fun.

On their website is also benchmarks about different RAID levels, so you=20
can compare them.
