Eye-Fi has launched the Pro X2 16GB, its largest Wi-Fi SD card, and its fastest yet. The Pro X2 retains all the existing capabilities of the existing 8GB version, including upload to a smartphone, direct connection to a Wi-Fi network, auto backup and Raw file transfer. Despite the capacity and speed hike (the previous version was rated as Class 6), the Eye-Fi Pro X2 16GB retains the recommended selling price of $99.99, with existing models having $20 knocked off their prices. Customers in Australia and Japan will be next to receive the card.
