Hello everyone. I just upgraded to a Seagate momentus 7200.4 500GB and 4GB of Crucial ram. I also cloned my old hitachi(5400 250GB) to the new HD, but I haven't noticed any difference in speed. Are there any processes I need to follow? I have repaired permissions, cleaned user/system cache etc, but it's still the same. Could it be because I didn't clean install MacOSX? Thanks in advance.
