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.
