If your second non-OS drive is used for data/games, you are better off enabling rapid on the non-OS drive for the following reasons.

The magician rapid service is enabled after boot and does nothing for boot speed.
Most software requires minimal read/write volume (obviously with some exceptions).
The highest read/write activity occurs with your data which is located on your data Samsung SSD.
