Dedicated Hosting Bandwidth

how much bandwith dose Myspace allow in a month.?
I want to create a free website somewhat like Myspace, but how much bandwidth should i buy to host a site where people can upload photos and video. For example a dedicated server gives 400G per month is that enough? Thank you

It all depends on the size of the accessed files and the number of users. A dedicated server will work great for a startup. By the time it starts getting bogged down, you should be making enough ad money to get another server for overflow.
