A terrabyte is doable today. But it will take a _long_ time to produce all of them. And it is going to take a monster machine with a lot of RAM and very fast disks to pull this off. Remember that several sixes were computed on a Cray a few years ago. But we still don't have that kind of computing power in the PC by a very long shot.
