I've got 2 x 500 GB SATA's in my notebook. I'm the type of guy who is a minimalist PC wise; I keep only essential data on my systems, the rest goes on network or other external drives. The second drive is used to constantly update the first using an imaging utility. I've always got two backup copies of all drives in my house. My family relies on me to keep things flowing and I got tired of hearing my daughters crying over lost data.
