Flashdisk

USB flash drive (USB flash drives are often also called flash or UFD) is a data storage device NAND type flash memory that has an integrated USB interface. Flash drives are typically small, lightweight, and can be read and written with ease. As of November 2006, the available capacity for a USB flash drive is from 64 megabytes to 512 gigabytes. The amount of media capacity is dependent on flash memory technology used.

USB flash drives have many advantages over other data storage devices, particularly the floppy disk or compact disc. The tool is faster, smaller, with greater capacity and more reliable (because it has no moving parts) than floppy disks.

However, the flash also has a short life data storage, data security on the flash usually an average of 5 years. This is due to the flash memory used does not last long. Compare this with the hard drive that has a resistance of up to 12 years of data, CD / DVD-quality (and well-known brand) for 15 years if it is stored properly.
