Also known as jump drives and USB drives, flash drives provide removable data storage using flash memory. The drives are much smaller than the floppy disks that preceded them, while providing exponentially larger amounts of storage. Flash drives are also rewritable, a feature that some CDs and DVDs of comparable size lack. Though most drives have a capacity value printed on their exterior, the only way to check the true size of the drive is by verifying the value from your computer. The process is quick on both Windows and Mac operating systems. Writer Bio
