I read a previous thread (which I can't seem to locate at the moment) about a company named microsatacables.com and their development of an adapter to convert the SSD blade drive in the 2012 iMac to a SATA port in order to allow someone to install a 2nd SATA drive inside their iMac. I stumbled across their website today and noticed the product has recently been released: http://www.microsatacables.com/sata...l-ssd-drive-kit-for-imac-27-inch-2012-model/# The item is listed as a kit for the 27" model. Would anyone here know if it will also work with the 21.5" model? The site also does not specify is it is a SATA III connector. I emailed microsatacables about these questions I have and am waiting for a response. I figured I'd post this info here to see if anyone else has contacted them about this product.
