Sorry if this has been asked before, I did a search, but couldn't find anything very close to my question. I just installed an optibay in my 2010 17" MBP. I left my original 500Gb 7200rpm drive in it's original spot, and put an OCZ Vertex 2 120Gb in the optibay. The OS was installed in the optibay, I moved my home folder to the HDD (which I'm now seeing may not be the best thing to do) Basically, the HDD is spinning quite constantly, so it seems to be eating my battery rather fast (I'm seeing a loss of over 3 hours per charge). So I'm just wondering what the best setup would be, efficiency wise, I have quite a large iTunes library, FCP Scratch, and ~4Gb iPhoto library as well. Thanks a lot!
