1. A USB flash drive consists of a NAND-type flash memory data storage device integrated with a USB (universal serial bus) interface.

2.. USB flash drives are typically removable and rewritable, much smaller than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and weigh less than 2 ounces (56 g).

3.USB flash drives offer potential advantages over other portable storage devices, particularly the floppy disk.

4.USB drives with USB 2.0 support can also operate faster than an optical disc drive, while storing a larger amount of data in a much smaller space.

5.A flash drive consists of a small printed circuit board protected inside a plastic, metal, or rubberised case, robust enough for carrying with no additional protection — in a pocket or on a key chain, for example.

6.The USB connector is protected by a removable cap or by retracting into the body of the drive, although it is not liable to be damaged if exposed.
