Floppy Disk vs USB.

  The USB (Universal Serial Bus) Flash drives are small storage devices which can store large amount of data in the form of flash memory and are portable. They are available in different sizes varying from 256MB to 64GB. 

The history to when the USB pen drives first came in existence is quite controversial; however, it is said that the first commercially-available USB flash drive was called the "ThumbDrive," it was produced by Trek Technology in the year 2000. Soon IBM came out with its own model known as the "DiskOnKey". By 2002, there were several companies which entered the market producing a similar product and marketing it.

   Pen drives comparatively have a much larger size than a usual floppy disk, which has a maximum data capacity of 1.44MB, or a compact disk, which has a maximum capacity of 700MB. This invention was a vast transformation from the era of floppy disks, as people required a device that would have a larger memory and yet be portable. The previous technology could only be used to store small size data for a short period of time that is 3-5 years, while Pen drives can store much larger size data for at least 10 years and no special care is required unlike in the case of CDs. The latest pen drives consist of a built-in MP3 player and finger print scanners. They only concept of "data storage" seems to be common between both the technologies. This technology highly attracted consumers as it made large amount of data transfer possible, which would otherwise be very expensive to carry out.

  Technology advanced from the era of Floppy disk which was then replaced by hard disk drives, ZIP drives, optical drives and USB Flash Drives; however, another method of storing data information is by “Storage Cloud”. So what will be next big thing in the next ten years? You will never know in the world of technology.
