John,
I'm getting about the same thing. 12MB/S if I don't mess with
settings. Up to about 14MB/S if I do.
I did notice that my SATA drive doesn't report as many udma modes
as my other drives and is hence set to a slower mode:
myth12 ~ # hdparm -i /dev/hdc
/dev/hdc:
Model=WDC WD1600JD-00HBB0, FwRev=08.02D08, SerialNo=WD-WMAL93597321
Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74
BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2
AdvancedPM=no WriteCache=enabled
Drive conforms to: device does not report version:
* signifies the current active mode

Maybe there's somethign about the current ATI IGP chipset driver that
doesn't do the best at getting speed out of the drives?
