I have an SQL table with the following structure:

Code1 - int
Code2 - int
Val1  - real
Val2  - real
Val3  - real

There is only one index (clustered) were Code1 is the first indexed column and Code2 is the second. The size of a single record is 20bytes.

I need to be able to store around 150,000,000 records and the biggest select operation would be on 500,000 records. I assume that the size of the table will be around 3GB

I would like to know if this design will work or there might be ‘unexplained’ problems or slowdowns when dealing with such a big table.
