A Long-winded Addition
I installed the Dual Drive for the always-available Time Machine backup. Optical storage really is antiquated.
The installation went perfectly, however certain bizarre issues resulted. My MacBook Pro seemed to no longer go to sleep, preferring instead to shut itself down, then complain to me upon boot that this had happened. Additionally, Bluetooth would inconsistently report itself unavailable. After some light reading, I reset the SMC, PRAM, reinstalled Mavericks 10.9.2 and recovered my setup via Time Machine, and reflected seriously on whether or not I needed Bluetooth or suspend mode for my laptop.
The solution (so far, anyway) seems to be to shutdown the computer, disconnect the SATA connector to the Dual Drive, reboot, suspend, reconnect the SATA, then restart. That solved the problem for me.
I have no way of knowing what the cause of this issue was and I may never know. At first I thought it might be related to the amp draw via SATA possibly sharing a power bus with Bluetooth. Now I think it may have been Mavericks confused by how a SuperDrive miraculously became a hard disk. I believe the problem is resolved.
