I've been reading the huge SSD threads and decided to purchase a Samsung 830 for my '10 MBP 15" (arriving tomorrow!)... should I update the firmware? is it a necessity? do people recommend it? I know that Windows is required. Also, are there any downsides to installing the old drive in the optical bay? I haven't used the optical bay in years and have no problems getting rid of it.. will OSX ML put the HDD to sleep properly? Any battery life problems? What issues have people experienced? I feel like putting the old/slow drive back in is sort of counter-productive.. I could get buy without the space, but it would be nice.. Any thoughts? Thanks!
