You’ve hit a known issue within some MacBook Pro systems!
Review the Red notes here [https://eshop.macsales.com/item/OWC/DDAMBS0GB/|OWC - Data Doubler] The issue is the system not the carrier. The Optical drive bay is just not able to run at SATA III (6.0 Gb'/s)
To add to the problem your Samsung SSD being an auto setting drive (one that is able to match up with the systems SATA ports data rate) is unable to sync up with the port so it makes this worse. You’ll need to get a fixed SATA II (3.0 Gb/s) drive to use your optical drive port like [https://eshop.macsales.com/shop/internal_storage/Mercury_Extreme_SSD_Sandforce/Solid_State_Pro/|OWC - Mercury Extreme SSD].
Don’t even think about swapping your HDD drive to the optical bay, as you’ll be only putting it at risk! The HDD bay has special crash guard services to protect your drive when you bang your system or put your system into sleep mode and move your system about.

OK, if your system is not marked with a Red note then you do have a system which is able to support SATA III I/O (6.0 Gb/s) don't trust the hardware profile. Just because the PCH offers SATA III (6.0 Gb/s) the drive link speed is what you need focus on with the Optical bay drive. If it does not link up at SATA III (6.0 Gb/s) then you still have an issue with the bay)

As far as the HD bay you likely have the original SATA cable which was only rates for SATA II (3.0 Gb/s). You'll need to get the newer version of the cable [product|IF163-041-2] This cable is the better one the (and yes! its for the ‘12 model). You also want to place electricians tape on the uppercase where the cable crosses over as the rough surface of the aluminum case often kills them. Lastly, you’ll want the arc the corners don’t bend them into tight creases! The foil wires inside will be damaged!
