The 2011 13" models are sata 3 in both bays according to OWC and they've raided two SATA 3 drives in those.
SSD certainly didn't work as intended when placed in the ODD bay of my new 2012 15" MBP.![]()
As noted by someone else above, some early 2011 13's have SATA 2 in the optical bay (including mine, I checked!).
What specifically wasn't working for you?
