250+160+160+12= 582GB. One of my 160's is on the fritz, and I dont really use the 12, But I use the others. Its nice I never look at how much I've filled up, I'm only using about 100gb right now but I just reinstalled so I have no music or anything. Gonna try and get on Ubernet with my buddy maybe to get some specific stuff. Probly gonna be vid editing soon as well.
