Again, thanks.

Some thing else comes to mind:

The cache unbound keeps: is it only in memory or does it write to disk? If it's the latter, I think I'd be advised to change the default or use a symlink so that the data goes to the attached external hard drive rather than the sd card that is serving in place of a hard drive (housing the OS) on the plug.

Am I thinking appropriately in this regard?
