You aren't going to be able to get the exact output you want with the standard Unix/Linux commands very easily, if at all. Mapping disk I/O by process is not a trivial task.
If you are using
Solaris 10,
a Dtrace script can probably be developed to do this:
DTrace at OpenSolaris.org
(see the scripts section - there are some examples on Brendan Gregg's page that are close to your request).
If you are using
HP-UX, you could develop a custom measureware/glance script and syntax file to get stats close to what you need.
Not sure of what you'd need for Linux to be able to get this data, but it's most likely going to be add-on.
Edit: Glance is available for RHEL

5. Filesystems, Disks and Memory
Hi All
I was wondering how the copying of vast amounts of data affected the overall lifespan of an HDD.
In my example, I'm copying approx 120GB (250,000) of files, once per hour from disk to another.
Is this likely to have a detrimental effect on the disk in terms of reads/writes etc?
