SATA has performance standards just like PATA & SCSI.  If the onboard 
supports SATA-II, then the performance should be as good as you're going 
to get.  On the other hand, if you add a PCI-E SATA controller, and it 
doesn't support SATA-II, then the performance will be worse.  In other 
words, you need to look for which SATA spec is supported by the 
controller, and then get drives that match that spec version.
