I'm not asking how to find out where a bottleneck is. I just what to know how to check if the harddrive is being used at its limit (and hence causing a bottleneck).

Something like top where I can see a usage percentage of CPU and RAM.
Is there something like that with which I can monitor harddrive activity?

Native linux tools preferred.
