UHS-II provides bus speeds of up to double those of UHS-I by employing two rows of pins for data transfers. When operating in Half Duplex mode, the UHS-II bus employs both rows to transfer data in the same direction, allowing the card to achieve sequential transfers with read speeds of up to 300 MB/s and write speeds of up to 280 MB/s. This means that the user can shoot video at incredibly fast speeds. Alternatively, the UHS-II bus can also operate in Full Duplex mode (at half the speed of Half Duplex mode) whereby each row transfers data in the opposite direction at the same time, allowing for the movement of content from the host to the card and vice versa, simultaneously. This allows the user to execute two tasks at once, dramatically accelerating the speed at which they can execute post-production editing activities, translating into incredibly efficient workflows.
