Attached is the dmesg for that box, note how both ad0 and > ad2 are shown as UDMA100.. You need to go -current to get the reported interface corrected. Anyhow, the SATA interface always runs at 150MB/s. However if your disk is not a native SATA disk but one with a PATA->SATA dongle on it, the speed between the dongle and the disk wil be whats reported and limitting your transferrates... -- -Søren
