I think this depends somewhat on that problems one wants to solve. E.g., for the 2 terabyte compressed Stein-Watkins elliptic curve database, the main thing that came out of it was a Bulletins paper that basicaly involves a bunch of SQL queries through the entire dataset. That is only possible to do if one has the complete giant download. >> And is 20GB of data too much for an spkg? > > Yes.
