simple speed test ... ( must write and read at the same time )
- only using hda ( say ata-100 or ata-133 device ) ... no hdb connected
date
while ( do it 100 times )
# if your disk has spare space
tar zcvf /opt/test/giant.tgz --exclude /opt/test/giant.tgz /
#
# if you disk not NOT have spare space
# tar zcvf /dev/null /
#
# flush the system so it doesnt use data in your 2GB of memory
#
# more test
ls -laR / > /tmp/test.ls.log
#
done
date
- now connect hdb ( like a slow ata-33 cdrom )
do the same tests
- see the time difference
