Alienware 17 - Installing a 2.5" SSD in the optical drive bay

Hello everyone, I got excellent help last time and I am hoping I can get it again. I have an Alienware 17 with 2x 750 GB HDD in raid 0 and a 256 GB mSata card. I purchased a 500 GB Samsung 840 Evo SSD on a very good Black Friday deal.
Finding reliable info online about the Alienware 17 is proving to be a challenge. I have seen allusions online of people who are running 3 SSD drives or 3 mechanical drives. Also, if you go onto the dell website that sells PCs to the middle east and use the configuration tool for the Alienware 17, you can install 3 750 GB HDD in Raid 0.
Unless that is a misprint then I have to think that the third drive is installed where the optical drive goes. When you take apart the system, the optical drive sits in a bay that is much too large for a 2.5 inch drive. I have looked online at possible drive brackets and mounts but I have no idea what will fit.
Also, the cable that goes to the BD is one I have not seen before. It is definitely not a Sata cable.

So my question is, can a third drive be installed where the optical drive goes? If so, what mount do I need? And do I need to install a new cable or can I get a converter for the existing cable?

Thanks in advance for any help.

6CTX5 2ND HDD Bracket for ODD bay

Thanks

 

Thanks, I saw that after I posted. Can someone link me to a good part? The only ones I found after a search was on Amazon but they have horrible ratings and I hesitate to order one.

 

I would recommend to install the SSD on the regular HDD slot and any regular HDD on the ODD side.
