What you just wrote would account totally for the bad numbers IF you
are getting which drive is which mixed up in your benchmark results.
PIO mode is dog slow. Are
you SURE, I mean, REALLY, REALLY sure that the SATA drive is the
one with the slow banchmark?
What exactly does DM say your drive controller is (chip number)? If it's an
Intel,
I would go to
support.intel.com and see what's new. I would NOT
trust Dell to be up on this.
