We can categorize primary storage as volatile random-access memory, which loses its data upon power loss, and nonvolatile memory, such as flash and read-only memories, in which data persists.Data transfer forms include floppy disks, CDs, DVDs, and flash memory cards.Fast random-access forms include disk drives, flash memory, and the slower DVD-RAM. Data archive forms include tape, CD, and DVD.IBM's Millipede prototype exemplifies high-density nonvolatile erasable memory suitable for portable digital systems, and thus targets the flash memory market. The latest in a continuing line of storage technology innovations, Millipede consists of a prototype microelectromechanical system that provides a terabyte of storage on a single chip the size of a postage stamp.
