Around 120 users will be connected direct, and 200/300 will be connected trough ASP.NET with pooling.

Lots of activity and data. Data because in 30 tables will be inserted more than 500.000 records, one table of them will have more than 300.000, and activity because each inserted record will be updated at least 10 times, and will be accessed to read it a minimum of 100 times.
