Here is what I found about it:
Cards that comply with UHS show UHS-I or UHS-II on the label, and report this capability to the host device. Use of UHS requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation and select the 4-bit transfer mode.
To shed more light on this ... it's one of the UHS-I cards (http:// www.sandisk. com/products/ memory- cards/sd/ extreme- uhs-1-45mbs/) 32GB option.
