I can highly recommend the Areca family of SATA-II controllers. I have a
ARC-1110 (4 poort RAID controller) with 4x 320GB Western Digital
SATA-II drives attached to it in a RAID5 configuration.

Simple dd(1)-ing gives around 100MB/sec read and 70MB/sec write
performance. You can use sysutils/areca-cli to monitor it and update
settings (I have never tried actually creating arrays there though).

The controllers are a tad expensive, but once you have one, you won't
reget it.

I have 2 arryas of 4 WD320G drives each running RAID0 (I have backups I just 
need the speed).
