Steps to reproduce the problem:
1. Start Chrome
2. Download something
3. Watch HDD usage

What is the expected behavior?
HDD isn't permanently on 50%+ usage.

What went wrong?
Screenshots: 
when HDD usage is high: http://prntscr.com/gjc8uw
after the problem 'dissolved': http://prntscr.com/gjc9xb

This all happens after I've started a download, even after the download has finished. However, once the usage goes down again (this goes on for many minutes), the second download won't trigger the 'something' again.

I've also tried disabling my Anti Virus program (Avast! Free), however the problem still occurs.

This high HDD usage also prevents favicons from loading (on new tabs).

Did this work before? N/A

This is an issue I've been watching since a few months. I don't really know when it started.
