If you decide PostgreSQL is right, I'm sure the advocacy mailing list would like to see your case study when you are finished. Your hardware requirements mostly depend on how you're going to use the data. If you expect that most of the data will never be read, and that the database will be more of an archive, the requirements might be quite reasonable. However, if or when you do need to search through that data, expect it to take a long time. Regards, Jeff Davis
