Try mounting your filesystems with the 'noatime' option. 

By default, each time a file is accessed, regardless of whether it is
already loaded into memory, the kernel will update the access time file
attribute, causing a disk write. Most people don't ever use this
information so it should be safe to turn it off.

I shouldn't think this would be the cause of all the disk activity but
you should see a noticeable reduction (as I did on one of my systems).
