Instead, if you have high requirements on capacity, purchase hard disk which is much cheap per gigabyte. What's more, the speed of the flash memory is limited. The operations and features are quite similar with that in hard disk: operation speed on small block is slow, and operating speed on large block is fast. Memory cards enable mobile users easily to transport digital photos, music, or files to and from mobile devices and computers or other devices. Compact Flash memory cards are also very common, as these are often used in Digital SLR cameras. While addressing, the NAND flash memory uses 8 strips of I/O interface data cable to transfer the address information packet.
