I tried to split HDs evenly between those 2 adaptors , so what I had were 2 wide HDs on the first adaptor, amnd 2 on the second. Read peaks at 12+Mb sec with 16 in /etc/ccd.conf Write peaks at ~13Mb/sec with 512 in /etc/ccd.conf Trying to optimize both , I ended up with 128 and 9.5-10Mb read/write. Looks stable , easy to configure and well, fast :) During the test I've played with 120Mb - 400Mb big files, run 4 simultaneous "tar --unlink -xvf 32.meg.big.tar.all.different" trying to trash it. Works just fine I'm trying to get "bonnie" installed , BTW what is the official site for it ? , so I'll report bonnie's results here later PS - Tried it on P6-150Mhz from ASUS - no luck there. Braindead PCI implementation is SLOW !!! Don;t but it yet ! Or , at least call Intel and ask for Alder :)) - may be then we'll be able to get the thing :)) Rashid
