I had a client that tried to use Ms Sql Server to run a 500Gb+ database. 
The database simply colapsed. They switched to Teradata and it is 
running good. This database has now 1.5Tb+.

Currently I have clients using postgresql huge databases and they are 
happy. In one client's database the biggest table has 237Gb+ (only 1 
table!) and postgresql run the database without problem using 
partitioning, triggers and rules (using postgresql 8.2.5).
