Can I use a mSATA drive to create a Fusion Drive in my iMac? I have a Samsung MZ MPA1280/0D1 128 SSD mSATA drive. 

Can I use this to create a Fusion Drive in my 2011 iMac 27" and, if so, what cable will I need in order to connect the mSATA drive properly?
Apparently with this iFixit upgrade kit you can add a second SATA drive:

You'll have two drives as well as a functioning optical drive. All you need is an extra 2.5" SATA drive (not included).
