I just replaced my optical drive in my 2010 macbook pro 15 inch with my old 500GB hard drive that used to be in the HDD bay and placed a new SSD in the HDD bay. Now i have 256 GB of SSD storage which i would like to use for only my operating system and applications.
The rest of the data (music, movies, text files, pdfs, etc) i would like to be stored on my other Hard drive.
I reformatted both hard dives to be Mac OS X Extended (journaled) and am currently installing the SSD with OS X Yosemite.
How do I tell my mac that i want to install apps on the SSD but storing music and other stuff should be done on my HDD (which now is in the optical bay).
