We have already seen Samsung's Ultra High Speed Class 1 (UHS-1) 16GB microSD card-- but at IFA 2012 the company has UHS-1 SD and microSD cards in 64GB capacities.
Available in "Plus" or "Pro" classes, the cards can handle read/write speeds of up to 80/40MB per second (SD) and 70/20MB per second (microSD).
The UHS-1 interface is ideal for LTE (Long Term Evolution) smartphones and tablets, allowing high-quality image and video playback directly from memory cards.
Currently only SDXC and SDHC cards designed for pro-camera use carry the UHS-1 designation.
