Would it be possible to slot more than one drive into a MacBook Pro's optical drive bay?
Obviously, no such product yet exists. (Would love to know if I'm wrong!) But when looking at optical-drive-bay-to-2.5" drive brackets like the OWC Data Doubler http://eshop.macsales.com/item/Other+World+Computing/DDAMBS0GB/ it's hard not to notice the empty space left over in the bracket even when a 2.5" drive is installed in the bracket.
It's hard not to imagine a similar bracket that would allow you to fit a 2.5" drive plus a mSATA drive simultaneously. Or perhaps two mSATA drives and no 2.5" drive.
Would the SATA connectors in a MBP (or any other laptop) allow for that? Or would each of the SATA channels on the MBP's logic board only support a single device each? Again, I'm just asking if such a product would be feasible or if running two drives off of a single MBP SATA connector would be a total non-starter.
Note: if this possibility interests anybody, it's worth noting that certain laptops like the ThinkPad W520 do make this kind of thing possible - the W520 has 1 SATA bay + 1 built-in mSATA connector + 1 optical SATA bay.
