I followed people's suggestions from the site here and bought an external hard drive to give me more storage capacity for recorded tv and for my music library. My internal hard drive is 78GB or so and it was always getting close to max capacity. Therefore I would need to erase shows to create more space. I bought a Seagate 750GB device, and it installed with great ease. I configured Media Center to save on the new hard drive when recording tv, but I am not sure about My Music, My Pictures, and My Videos. Should I even worry about these categories being on the external. I want the main system to runs as fast as possible. I am interested in people's opinions.
