I didn't see atime mentioned on the wiki page. Logging in fails for me right now (takes forever), so perhaps somebody else could add this info:
If you're looking for something that definitely does cause disk activity every 30 seconds, it's atime updates. When enabled (which they are by default), access times are updated for all file system _reads_ (even from the file system cache), and they are flushed very soon after (30 seconds AFAIK). If the problem really is that something is accessing the disk very often, atime is at least one of the most likely culprits. Mounting all filesystems noatime (or at least relatime) could make a big difference.
