My experience is that freezes are almost always associated with the hard drive 
having spun down, and needing to spin up before something can be read from the 
disk. (It just happened, as I was typing that sentence.) Tweak power settings 
to make spin-downs more rare, or banish them altogether if you're willing to 
take a minor hit to power consumption.
