I know that its better to have all primary, clustered, non-clustered indexes in a different filegroup than data, but what I want to know is:
1. Should that be on a separate drive altogether for getting good performance?
2. If the Data and index is on the same drive, is that okay and/or what are the recommendations if I cant put indexes on a different drive.

Some feedback:
1) The Clustered index is where the data is; a Non-clustered index can put on a separate filegroup
2) The performance boost would come from having the data and indexes on separate physical drive; you would need them to be in separate filegroups in order to get them on separate drives.
3) How big is your data? There might not be a big boost if your data is small.
4) If you can't put them on separate drives now, you might still put them in separate filegroups so that you could easily move them at a later time. I don't see a drawback from having them separated.
