I have a 17" Late 2011 MBP and I wanted to put a second hard drive in it. The trouble is, the caddy I have (this one here, got good reviews) and the 750GB drive that came with the MacBook don't fit in the optical bay without severely pushing against the keyboard and the bottom panel. The Samsung 830 I was going to use as my main drive fits in the optical bay perfectly fine though, being slimmer than the standard HDD. I know I would lose some performance running the SSD in the optical bay but is it safe? Is it stable? Could I still configure it as the main drive even though it wouldn't be in the main slot? Thank you all.
