Background: I have a friend who purchased a caddy to install a second hard drive in his MacBook. One drive is, of course, the original 250 GB Hitachi hard drive and the other drive is a 60 GB OCZ SSD. Question: Which goes where? (I'm doing the installation and) I was thinking about putting the SSD in the traditional hard drive location and the Hitachi HDD in the Super Drive caddy but I was worried that the Hitachi HDD's temp, speed, sleep status, and shock protection is controlled and controlled specifically over the SATA cable located in the original HDD location. Simply, I know that the SSD can handle being in the caddy (whether or not that's the ideal location for speed, I don't know) but I'm unsure if the Hitachi could handle being in the caddy. Of course, he's worried about things like battery life and heat, as well, and if the caddy location can't control the Hitachi's sleep status correctly, then that would harm battery life even more, I'm sure. Note: In case you're wondering, the SSD will be the boot drive.
