I installed it on the Optical Bay with the Data Doubler. I bought a HGST 1TB 7200, 6Gb drive 10 months ago from Amazon (the exact same, as recommended by OWC).
LATE 2011 MACBOOK PRO SSD DRIVE UPDATE
MacBook Pro 2011 Models and SATA 3.0 (6.0Gb/s) – Update – ), finally gave light to what happened.

Optical Bay with Data Doubler = 6Gb/s Good MacBook Pro 13” October/2011 models (2.4GHz and 2.8GHz).Future updates may resolve some fringe issues for those models, but, unfortunately, testing across a significant number of both Early and Late 2011 MacBook Pro models indicate that 6Gb/s is only stable in the main bay of 15” and 17” models, while optical bay 6Gb/s is reliable for 13” models only at this time. While it had been a long road with various frustrations in terms of using a 6Gb/s SSD in even the main bay of the previous 15” and 17” models – Apple’s EFI 2.2 update resolved most of those issues. This is the same as drive setup/configuration we saw in the the Early 2011 MacBook Pros. Although still unstable in the 15″ and 17″, the optical bay SATA signal has improved considerably and we are looking into possibilities that might make 6Gb/s in this bay reliable. Just like the Early 2011 models, while we continue to see reliability with 6Gb/s in the optical bay of the 13″ model – the optical bays of the 15″ and 17″ models remain too unstable for 6Gb/s drive use. Right out of the gate all of these models are proving 100% reliable for use of a SATA Revision 3.0 hard drive or OWC 6G SSD installed into the main drive bay. These units all show 6Gb/s link capability for both the main drive bay and the optical bay. As we mentioned last Monday, Apple has released new “speed bumped” MacBook Pro 13″, 15″, and 17″ model laptops.
