A USB flash drive

A USB Flash drive is a small device that stores information and files from a computer. Flash drives are an easy way of moving data between different computers or devices to be read or edited. Flash drives are connected to a computer using a USB port, which can be found on many devices. Flash drives take their name from the flash memory used to hold files. Flash memory is a type of memory that does not need any moving parts, unlike a CD or Floppy disk.
The capacity of flash drives starts at few megabytes. In April 2010, the ones that could hold most data could hold about 256 gigabytes.
Other common names for a flash drives include: memory stick, keydrive, pendrive, thumbdrive and jumpdrive or simply USB.
USB flash drives have some advantages over other portable storage devices. They are much smaller than floppy disks, and can hold much more data. They do not have moving parts, so they should be more reliable.
