In addition to enabling higher data rates, the UHS-II interface allows for lower interface power consumption, lower I/O voltage and lower electromagnetic interference (EMI).SD card speed is customarily rated by its sequential read or write speed.Windows Vista (SP1) and later However, SDXC cards can be reformatted to use any file system (such as ext2, UFS, or VFAT), alleviating the restrictions associated with ex FAT availability.Nevertheless, in order to be fully compliant with the SDXC card specification, many SDXC-capable host devices are firmware-programmed to expect ex FAT on cards larger than 32 GB.

The three form factors are the original size, the mini size, and the micro size.

Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices.

The standard was introduced in August 1999 by joint efforts between San Disk, Panasonic (Matsushita Electric) and Toshiba as an improvement over Multi Media Cards (MMC), and has become the industry standard.

Double data rate operation at 50 MHz (DDR50) is also specified in Version 3.01, and is mandatory for micro SDHC and micro SDXC cards labeled as UHS-I.

In this mode, four bits are transferred when the clock signal rises and another four bits when it falls, transferring an entire byte on each full clock cycle, hence a 50 MB/s operation could be transferred using a 50 MHz clock. The physical interface and pin-layout are the same as with UHS-II, retaining backward compatibility. Use of UHS-I requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation over the I/O interface pins and select the four-bit transfer mode, while UHS-II requires 0.4-volt operation.
