Separate indexes from data for improved performance

Expert Jeremy Kadlec determines that it is beneficial to split that data from seperate file groups for improved performance.

Is it not ideal to separate the indexes from the data for improved performance? What would be ideal in this situation?
Yes -- from an idealistic perspective it is beneficial to split the data from the indexes in separate file groups for large databases with hardware with numerous controller cards and hard drives to split the IO. I would test the performance with your existing hardware and database, then make the change to see the performance gain. Good luck!
