CompactFlash is the world's most popular removable mass storage device. The CompactFlash card is about the size of a matchbook and only weighs half an ounce.
CompactFlash technology has resulted in the introduction of a new class of advanced, small, lightweight, low-power mobile products that significantly increases the productivity and enhances the lifestyle of millions of people. These products include digital cameras, digital music players, desktop computers, handheld PCs (HPCs), personal communicators, Palm PCs, Auto PCs, digital voice recorders and photo printers. SanDisk, the inventor of this product, has led the market for CompactFlash since its inception.
