I wanna buy an OptiBay and move my 500GB HDD to the optical drive slot and use a 120GB SSD as my primary drive for the system and the apps (leaving the home folder at the HDD). If you have this set up and experiences, would you try to answer my questions?: How is the battery life affected in real life? I understand that you now run two drives and that will account to some battery drain. I've heard that fans can go like crazy with this set up. Is that correct? Do you think it's safe to buy "cheaper" alternatives? Such as this one? Or do you have good experience with some other "cheap" ones? Thanks!
