SanDisk was the first to introduce SD cards that also featured a USB connector. Now Buffalo has introduced a line of similar SD cards. Rather than folding in half to reveal the USB connector, the Buffalo USB RSDU memory cards come with a cover that you remove to reveal the USB connector.
Buffalo’s RSDU cards will be available in mid-July and will come in capacities from 256MB to 2GB. Pricing information is not available yet.
