Toshiba calls it an "innovative connector design" referring explicitly to the connector itself. You don't have to be a "reductionist" to see that it's not really that innovative. MicroSD cards have been using the hinged connector for years [0]. Now the fact that they connect this type of card instead of the other type of card is indeed new.

I appreciate them improving on the current situation and I love that I'll get SSD performance with SD convenience but it doesn't have to be innovative for me to do that.
