When I add a SATA port multiplier I see a dramatic decrease in throughput compared to directly connected SATA disks (not a big surprise, although the combined throughput is way below 3 Gbit/s). So now I am looking for an add-in SATA card that is supported by the FreeBSD ahci(4) driver. I don't need HW RAID support on the card as I'm running ZFS. I have PCI and PCIe (x1) slots free. I tried a Promise TX4 but that one appears as an ata(4) card and not as an ahci(4) card. Any ideas? Thanks a lot! Paul Schenkeveld
