SATA performance
 
I have a SATA ICH5 on a i865 chipset i think .... anyway, that doesnt matter, the drive works out of the box and so that is cool

anyway, i decided to get do some hdparm -Tt tests, and I was wondering if there was a way to tune the SATAs like you can with IDEs.

here are my results:
hdparm -Tt /dev/sda

/dev/sda:
Timing buffer-cache reads: 4120 MB in 2.00 seconds = 2060.31 MB/sec
Timing buffered disk reads: 174 MB in 3.01 seconds = 57.72 MB/sec

any insight into this would be nice.

There is no SCSI optimizations in LINUX. For your drive you reached the maximum data transfer although hdparm does only raw speed. You can use dd and time to give you estimate data transfer from /dev/zero to the hard drive. The more accurate way is use a hard drive benchmark utility like Bonnie.
