SD Gets Speedier

E-mail Print PDF

SD CardsThe SD Association announces its UHS-II bus-interface specification-- with HD recording speeds of up to 312MB/s.

The new protocol will make part of SD 4.00 specification, available later this quarter for SDXC and SDHC products.

A second row of pins on UHS-II cards carries the new high-speed interface signals. The interface does not effect current SD card form factors-- products will be available in standard full-size and micro formats.

This also means devices supporting the UHS bus interface will also be backwards compatible with existing SD memory cards.

Meanwhile the association also announces its eBook application specification-- giving ebook publishers access to SD-equipped portable devices.
