How to estimate server size requirements for MSSQL database?
===

I have spoken to a couple of server providers now trying to estimate the cost feasibility for a web development project but not really getting a clear answer.

The main burden of the project is the database which will hold 20 million rows of data with 5 columns per row (10 letter code, 10 letter code, 10 letter code, 10 letter code, 10 digit integer, URL (say 20 characters long on average).

The main question is how to estimate the GB of storage necessary for something like that? (with MSSQL). [I don't have a copy of MSSQL to test].

The second question really is about speed and I/O requirements, but that is probably a question way down the line after a demo is developed.
