It does take a good while to run tho. It wasn't to bad on my new rig but the old rig did take a little while. iozone -R -l 5 -u 5 -r 4k -s 100m -F /home/f1 /home/f2 /home/f3 /home/f4 /home/f5 | tee -a /tmp/iozone_results.txt & The results were much different than what hdparm shows. It shows the 3Gbs/sec like they advertise they can do. I wonder which is more accurate? :/ Dale :-) :-)
