RAID Controller for CentOS 4.3

I don't have too much exposure on different RAID controllers for Linux. Of course, I am a software developer not a systems administrator or not even a hardware specialist. And I have wasted so many hours trying to make one of our RAID'ed servers to work and only to discover that the card is lousily supported. So here's my recommended hardware:

3ware 9550SX, it's S$700 and it's worth it! I have searched tons of forums trying to get our crappy RAID controller to work but what's echoing in the community is the 3ware 9550SX. See, those wasted hours are meant for development work.
