Well I was looking for one of the wise (you7ng)old masters to answer. Since that did not happen, I just 'brute forced' a solution, that is optimal (hopefully) for my hardware. Here's what I did, so it may or may not help you. You can make adjustments to hdparm dynamically at the command line like so hdparm -c1 /dev/hda < your /dev/drive may differ so adjust accordingly> hdparm -tT /dev/hda < this perform a simple throughput test> hdparm -a 256 -m16 -c1 /dev/hda < make some adjustments and retest > hdparm -m4 -c1 /dev/hda < gave me the best results for my hardware> Thus my /etc/conf.d/hdparm file looks like this: # These setting for the 4 gig CF Sandisc card seem to be optimal hda_args="-m4 -c1 " If you really wanted to go all out testing, use bonnie or bonnie++, both are in portage. hth, James
