Which is why this review, with their SATA controller clearly being on a PCI bus, is flawed. If they were using a SATA controller on a PCI-X bus, they would get better transfer rates, since they were hitting the PCI bus limit.
You can plug in multiple cards into multiple PCI slots. If you attach their SATA connections to a SATA raid (or even non-raid) controller that is plugged into a higher pefromance slot, such as PCI-X or even a 64 bit PCI slot, you will most likely get better performance than this review leads you to believe. Their bottleneck wasn't this card, but the PCI bus holding the SATA controller they were using. This was obvious from the maximum transfer rates being close to the 125 MB/s theoretical PCI limit.
