Is the onboard SATA controller real SATA or just an ATA-SATA
converter? If the latter, you're going to have trouble getting faster
performance than any one disk can give you at a time. The output of
'lspci' should tell you if the onboard SATA controller is on its own
bus or sharing space with some other device. Pasting the output here
would be useful.

N00bee question:
How does one tell if a machine's disk controller is an ATA-SATA
converter?
The output of `lspci|fgrep -i sata' is:
00:1f.2 SATA controller: Intel Corporation 631xESB/632xESB SATA AHCI Controller\
(rev 09)
suggests a real SATA. These references to ATA in "dmesg", however,
make me wonder.

His drives are either really old and do not support NCQ or he is not using
AHCI in the BIOS.
