OWC's products
I've been reading this thread over the past few weeks. I want to thank you all for your advice, and to share my experience with an Optibay installation that I did last week.
I installed
OWC's Data Doubler on an Early 2011 MBP 15", and I'm impressed with the quality of the Data Doubler. It holds the hard drive in position using two screws, which feels very secure once assembled. I felt the Data Doubler was worth the cost over the options on Amazon, because it included all the tools you needed to complete the job. That's a personal plus, considering I didn't have any of the necessary tools available.
However, I purchased
OWC's SuperSlim for Apple's SuperDrive enclosure with the Data Doubler, which was not impressive at all. The SuperSlim enclosure fits the Early 2011 MBP's superdrive perfectly, but would not load any DVD or CD I threw at it. I tried plugging the SuperSlim into the Mac, and then a desktop PC in my house, but both would have the disc spin up, but then stop spinning, never to load, auto-play, or provide any signal that I introduced an optical disc to OS X or Windows 7. To rub salt in the wound, I would have to remove the SuperDrive from the enclosure, remove the Data Doubler from the Mac, and reinstall the SuperDrive to eject the disc.
I ended up returning the SuperSlim enclosure to OWC for refund, and am currently on the market for a worth enclosure for my evicted SuperDrive. I'll look through the thread again, but any suggestions are welcome.
TL;DR?
OWC's Data Doubler = Worth buying.
OWC's SuperSlim for Apple's SuperDrive enclosure = You're milage may vary.
EDIT:
OWC emailed me after my return and refund, saying my specific enclosure was defective. So, you're milage may vary. I ended up settling for a
knockoff enclosure, fashioned to look like Apple's external SuperDrive. Bought it off eBay for ~20
