Hi Dale,
as I know, the hd hardware can't nearly as fast as the bus speed
regardless whether it is 6GB/s or 3GB/s.
Quickly doing the same as you on my harddisk gave:
/dev/sda:
Timing cached reads: 6726 MB in 2.00 seconds = 3364.06 MB/sec
Timing buffered disk reads: 318 MB in 3.00 seconds = 105.93 MB/sec
The speeds of 6 GB/s or 3GB/s are only reached, when reading data
directly from the hd cache.
I dont know, what motherboard you use. But the settings you describe
seem to be identical to mine.
Important is:
In the BIOS go to the hd section and look, what the BIOS think the
speed of your hd is (3 GB/s or 6GB/s). When found directly set you
SATA chip to that speed. It is recommended to do so by the help of
text of my BIOS. I have a 3GB/s disk. And yes, IDE is ok.
Here you can find explanations about AHCI vs. IDE sata mode.

On my board (ASUS Crosshair IV Formula) it was said, that AHCI is
slower than IDE, but (!) is not due to IDE vs. AHCI but to a
limitation of the chip.
Look at the benchmarks above: There no place to go faster than that.
3/6 GB/s on cach read are standard compliant and ~100 MB/s is the
limitation of hardware normal people like you and me can pay for.
Plug on the front:
This seems to be E-Sata jack AND SHOULD BE CONNECTED INTERNALLY ONLY
TO AN E-SATA (not SATA) JACK ON THE MOBO.
In unmounted status: Yes it should be hotpluggable as USB. BUT dont
connect the E-SATA jack of the case to a normal SATA jack on the
board!
E-SATA != SATA !!!!

Sounds like I am normal on speed. Still wonder why they call it
"advanced" tho. Hype maybe? ;-)
I noticed when I did some searching that the eSATA connectors have sort
of a L shape to them. All the SATA connectors have a L shape to them on
my mobo.
I think for safety's sake, I think I will shutdown first. The biggest
reason I was wondering is because it is on the front next to the USB
plugs too. Just made me wonder.
