You should get out now before your very disappointed a 2TB node isnt gonna make much at all and when its full your not gonna get any new data. I got rid of a 1TB node that ive had for 4 years recently. With the newest payouts being changed its not worth it to run a node that is small it. And if your running more then 1 hd to get to this size your really not making anything because each hd uses more power then it actually makes.
