Is there an extra mSATA port in the 2013 Razer Blade 14"?

I looked at the teardown on here, and the author mentioned that he had put in a second mSATA SSD in there. On top of this, this review mentions a second free mSATA port in the device. Can this be used as a second drive slot, and if so, is there anything one should know about it before buying a SSD for it? (If it's mini PCI compatible, etc.)
