  1. First, it manages memory very efficiently, which can result in big performance improvements compared to T-SQL alone.
  2. Second, the graphical interface lets you build large, complex and reliable transforms much more easily than hand-crafted T-SQL.
  3. And third, SSIS lets you more easily interact with additional external sources, which can be very handy for things like data cleansing.
