Best way to measure disk bandwidth usage

I've got a couple of servers which I'd like to keep an eye on in order
to check wether their storage subsection is providing enough throughput
or wether disk i/o is their bottleneck.
I know how to check this wrt cpu usage, memory size, network throughput,
but I'm totally lost when it comes to disk i/o.
I can run top and press 'm': this will allow me to know which processes
are using disk the most, but not wether I'm exploiting the hardware to
the limit or just to a small fraction of what it can do.
bye & Thanks
