Speedy transfers - with USB 3.0 5Gbps throughput

USB 3.0 interface negotiates up to 5Gbps, which the manufacturer cites as roughly 170MB/s for compatible cards and hosts. Transfer rate depends on card speed class and host port capability.

Transfer from both cards to a computer at once, reducing downtime during busy shooting or travel sessions.
