Well I decided to try out the system encryption in truecrypt and so far so good. I have been using truecrypt containers for a long time, but I wanted to make my laptop more secure so I used the system encryption. Took about 4 hours to complete the system encryption and I used it part of the time during the process. My goal was to make the laptop data useless to anyone who might steal it and I believe that goal is accomplished now. I notice no drop in speed using the laptop with it encrypted. The system is still responsive and everything seems to be running as usual. The system is fairly new with a core 2 duo and 3gb of ram and Vista 32bit. Don't forget to backup all your important data though first just in case you want to try this!
