I doubt all 50TB was collected in the first year. The 2TB hard drive was released in 2009... 8 years ago. I would be willing to bet his stash increased at a similar rate to drive sizes, if for no other reason than the fact that NSA data collections increased at what is likely a similar rate over that time. A year ago 6TB drives were already widely available, so now you're down to 10 drives. In other words, a medium sized home NAS for most nerds.
