Yep.

Really?  You can get an Intel E7500 chipset with 3Ware? 
Cool!  Which models?

Oh, I know.

Oh, I've seen all sorts of such "selections" in my time.

Seems like the typo bug is going around.  ;->

They wish.  ;->

Then again, the ATA "controller" is rather "dumb" -- the NCQ
is on the IDE of the end-device.  It's not like SCSI where
there's an intelligent, hardware host.

The AHCI is supposed to be the software/host equivalent of
controlling up to 32 ATA devices with commands, etc...  But I
haven't seen much work well in that regard on even Windows.

Really?  Hmmm, I thought the libata guys were pretty happy
with them.  I could be wrong, as it's been 2nd hand
commentary.
