Genuinely useful and pretty damn innovative. Very rarely are such words thrown around in the world of SD cards, but OCZ's Dual SD cards are just that. It's a standard sized card, the sort that fits snugly into most cameras out there, but has no need of a card reader to get the data from device to PC.
Slip off the housing at the end to reveal the USB connection, slot it into a waiting USB port and you're away. It really is that simple, convenient and fast to use. We've been seriously loving it in the office camera.
