Linux and FreeBSD often share some driver technology. I have had extremely bad performance historically with onboard SATA chipsets on Linux. The one exception has been with the Intel based chipsets (not the CPU, the I/O chipset). It is very likely that you are having problems with the driver for the chipset. Are you running RAID1 in hardware? If so, turn it off and see what the performance is. The onboard hardware RAID is worse than useless, it actually slows the I/O down. If you want RAID with onboard chipsets, use software RAID, or buy an adapter from 3Ware or Areca for $200. - Luke
