While most of the data/files are stable, there's probably a few Gigs that come and go with fair regularity. I update the box very frequently (ports, docs and sources) so that adds to the churning I'm sure. I'll start watching for any performance hits the next time it gets over 95% full. I'm just a bit surprised that I've not noticed anything. Thanks for the response. Much appreciated.
