i'd say to be careful about that - i tried a sata3 on the optibay (granted, el cheapo from ebay) for a while, it works but would eventually break (disk not ejected properly after some sata errors). went back to the good old 750gb sata2 OEM and zero problems since that.
cheers
Thanks for the warning. The last time I had one was a 2010 MBP 15", and had the bay as well. I think the SSD was in the actual HDD slot, and I moved the HDD to the Superdrive sled. I do remember there being some idiosyncrasy with BootCamp or something (maybe DVD player) that was expecting that SuperDrive, but it wasn't a deal breaker.
So, do you think what I did in the 2010 would work with the MD101? 1TB hard drive in the Superdrive sled, and 1TB SSD in the regular hard drive slot?
