SD cards to become even faster

sd-uhs-iiiThe SD Association, a group of almost 900 companies which sets SD card standards, has announced a new standard, UHS-III, doubling the fastest SD memory card transfer rate up to 624 megabytes per second (MB/s).

Since the standard is fully backwards compatible, devices offering UHS-III bus interface will accept the billions of existing SD memory cards.

The UHS-III high-speed interface signals are assigned to the second row of SD memory card pins introduced with UHS-II.

This newest bus transfer speed option will be available in full-size SDHC and SDXC cards, as well as microSDHC and microSDXC cards. It does not change the physical size or shape of the cards.
