Thanks for the info.  It is good that there seems to be a PCI SATA card
that seems to work well in FreeBSD-stable.  Do you by any chance know if
the RAID mirroring function is implemented in the controller or in the
driver?  If it is implemented in the hardware, it is possible that during
disk writes the data is transferred across the PCI bus only once for both
drives rather than once for each drive.
