WHAT IS COMPACTFLASH MEMORY CARD?

CompactFlash (CF) is a very small removable mass storage device format used in portable electronic devices. First introduced in 1994 by SanDisk Corporation, CompactFlash cards are designed with flash technology, a non-volatile storage solution that does not require a battery to retain data indefinitely. CompactFlash storage products are solid state, meaning they contain no moving parts, and provide users with much greater protection of their data than conventional magnetic disk drives. They are five to ten times more rugged and reliable than disk drives including those found in PC Card Type III products. CF cards consume only five percent of the power required by small disk drives.

WHAT IS "X" SPEED RATING?

The "X" rating is a unit of measurement for the data transfer rate. It is commonly used for write speed, because users generally care more about how long it takes to write data to a Flash card when using it in a digital camera or cell phone. Typically, read speeds are higher than write speeds for Flash cards, so the write speed is more meaningful when measuring performance. The base rate is 150 kB/s, so for example, 20x = 20 * 150 kB/s = 3.0 MB/s.

The following table lists some common ratings and their respective maximum transfer rates.
