I just picked up a second SSD for my laptop and also the optibay. I placed the older OWC 120gb SSD in the optibay and installed the intel 120gb in the hard drive bay. I'm quite please with the setup but I started to think that it might be beneficial to RAID them. I understand that I'll not be able to apply any firmware patches as a RAID system won't allow for booting up to flash the firmware. I'll need an external drive for that. Plus bootcamp is a no go. I'll also need a bullet proof backup system which I have. I use TM for hourly backups and CCC for a system restore. My thinking is less about the performance gains and more about combining the two 120s to make an effective 240gb volume. thoughts and/or opinions?
