So what exactly does a Momentus XT do in the optibay
My Google-fu isn't turning up specifics on this issue - just people saying there are "issues."
So I'll just post my question - I've got a late 2011 MBP and with a Momentus XT 750 running perfectly as the main hard drive. I've got a 640 WD Blue in the optibay running perfectly also. I've just ordered an SSD (NewEgg has the Samsung 840 PRO for $199 today!) and would like to put the quicker Momentus in the optibay. And it has my existing BootCamp partition on it as well.
What problems may I encounter with this? From what I've read that MPBs older (than mine?) do not support SATA 6 in the optibay, but I figure the drive will negotiate down to 3 and be just fine. I can confirm that the negotiated speed of the WD there now is 3 and the link speed is 6.
I'd just do it and try, but putting a drive in the optibay is such a PITA, I'd like to hear from experience before I learn the hardway.

Putting the hybrid drive in the optibay will be just like putting the hybrid drive in the main bay. If you do not use it as a boot drive, it will still put your most commonly used files into the flash memory.

Some people have claimed that the MoXT won't work as part of a DIY Fusion drive because it's a hybrid, but this is an ill-informed view as the computer can't tell that it's a hybrid. To the computer, the MoXT looks like any other 7200rpm HDD, but with a MUCH bigger than normal cache.
So, the answer to your original question is that the MoXT isn't going to work well in the optibay your computer. The fact that your current WD Blue is reporting a 3GB/s negotiated speed suggests that it's a SATA II drive, which is fine in the 2011 optibay, so you'll likely just have to stick with that.

Thanks for the explanation!
I'm seeing that now ... just booted after switching the drives and, while the computer can see it and get sizing information, it can't read any data off of it. :P
Switching back now ... i'm getting good at this.
