I'll preface this thread by saying I've done a lot of reading on this subject, but I've been unsuccessful in getting my questions answered. I just bought a new MBP, and installed a 2nd HDD in place of my SuperDrive. The primary drive is my SSD, which is only 128GB. The secondary drive is a 500GB platter drive. My intention is to store all music, photos and movies on my platter drive, but leaving the OS on the SSD. I've seen some comments about moving the /Users folder to the secondary drive, but it seems like logging on and doing other basic functions would then be reliant on the platter drive, which I'd assume would reduce performance. Please help me understand what I should do - I'm really new to OSX and I have no clue where to go from here.
