I always carry one or two USB flash drives inside my computer bag and keep another one at home as a spare. Avid computer users know the importance of having a flash drive. You can store data and transport them anywhere you go. They're very handy, lightweight, durable, reliable and have the capacity to store data to as much as 32 GB and, probably, even more. Compared to the floppy disks (remember those days?) and compact disks, flash drives are durable and resistant to scratches. It is also easier to transfer files into the flash drive. Oh, yes, and they now come in varied shapes, colors and unique designs, too.
