SD Card Secure Digital Cards

(SD Cards) are widely used in consumer electronics such as photo cameras, smartphones, etc. They are available in different sizes, some of them very small. Transfer rates, however, are quite low, currently available SD card do not exceed write speeds of 20 Mbytes/second.

Flash Chips

Flash chips are available in different technologies, sizes, and speeds. Solid-state disks use flash chips that support the Open NAND Flash Interface [59, 60] (ONFI) specification. These are the currently fastest chips on the markets featuring write speeds up to 300 Mbytes per flash chip. Recently, Intel flash chips were measured with a write speed of 156 Mbytes/s, which is faster than a hard disk. In contrast to the other options, flash chips are not removable. In the next section, we discuss the properties and limitations of flash chip in more detail.
