Re: IDE hdd faster than sata? How come?

I guess. There was no X and DE running. I run hdparm a few times, with
similar results. But since it fails to talk to the sata disk for lots of
other commands, i'm begining to suspect this benchmark feature...

How good is hdparm benchmark for sata? What am I missing here?

IDE disk is SAMSUNG SP0802N, FwRev=TK200-04. 80GB. udma5.
Sata is SAMSUNG SP0812C SATA 80GB.
The only thing I found was in samsung website "The drive comes defaulted
to udma100. To enable udma133 refer to www.samsung.com.br". So far,
www.samsung.com.br gives me nothing.
Does anybody have a clue?
Was it a quiet system, with nothing else running at that moment?
I also tested the jumpers, but they are irrelevant for the sata disk.
