I need more SATA ports on my mobo, so I'm looking for a SATA controller suitable for Ubuntu 9.04. I've picked out the Rosewill RC-218 from Newegg. This controller has 4 internal SATA ports, and two eSATA ports. Can anyone confirm compatibility or have any recommendations for a basic SATA controller with 4 ports? According to the Newegg reviews, it seems to work.
