    I'm thinking of putting a 2nd SSD into my MacBook Pro to replace my Optical drive. My only concern is battery. I have the 240GB OWC right now and was planning to add a cheaper 120GB SSD.

    I get about 8hrs typically out of a charge. How would that change if I add a 2nd SSD?

    To simply answer your question, 2xSSD would use less power than one normal HDD. This is because SSDs mostly consume about 1/3 power of a normal HDD.
    Therefore: worst case scenario: your battery life will be the same.

    If you're thinking of doing this, I'd consider buying a duplicate of your first SSD, and then installing them in a RAID configuration. This will double the performance. The machine would be insanely fast. SSDs consume so little power, this shouldn't have a noticeable effect on battery life, either.

    Do macbooks support hardware raid with optibay or will it be software?

    Going off the OPs question; How badly would adding a secondary (standard) HDD effect battery life?

    ooo me wanna know too. i have an ssd and i wanna put my hdd in the optibay.

    or i might put the ssd in the optibay and put the hdd in the regular bay bc i heard that the optibay doesnt have some shock resistant thing the other one does?

    i would only be using the hdd for storage, im guessing i wont hear it at all if i set to sleep after like 5 mins? i love my silent mbp :)

    Yes, I think they do. When I looked into this, I found a couple of folks that had done it before. At least, I'm 80% certain that RAID is supported within the hardware/MBP firmware.

    My question is: Why?

    Unless you plan to RAID them... 2 SSDs make no sense.
