Thanks in advance.
this can be difficult. While the suggestions given so far have been really useful, one problem that has not been discussed so far is swapping. If you are using more memory than you have got (more virtual memory than your amount of RAM) then almost anything that you do will cause a flurry of swapping. You could then conclude that the last thing that you have done is disk intensive, when that is not really a good interpretation.
If you are using kde, the ksysguard tool is good as you can look at whether your ram is fully utilised with the same tool that you use to look at processes. You could even set it up to instrument the traffic into and out of partitions (although this gets hard to understand with intricate partition systems). Gnome has a similar tool, but I forget the name.
I've got one box that does more hard disk activity than I would like, but I know this is down to a dhcp error, leading to frequent writes to log files. So, another thing you might want to look at is whether you have any log files that are growing out of control.
