I am running Debian on a SATA hard disk (my motherboard has ICH5 and SiI3112 chipset)
Right now I am using the SiI3112 but in order to do that I had to install Debian testing
because Woody intaller did not have the support.


I should say that the performance of my SATA under Linux is inferior to that of normal
ATA and the data rate I get from my SATA is very lousy comparing to ATA.
I read somewhere that this is going to get fixed in future versions of the SATA driver !

I thought these are about to be expected (DMA on hd* disks, the sda disk is SATA, the hd* are IDE)), do you get different speed on SATA drives? I have intel D865PERL (ICH5).

/dev/hda:

/dev/hdb:
