What do you think is the main factor for the popularity of a pen drive? The answer is its functionality. Pen drives have become extremely popular, even much more that the compact disks. Pen drives use non-volatile RAM for storage of data which says on even without any power. The basic pen drive is popular because of its hardiness. It will survive even a wash in your washing machine along with your clothes. The endurance of a basic pen drive can be mind boggling. It will survive dents, drops and scratched which have always created havoc with the floppies. Another reason which makes the pen drive so popular is that it has much bigger capacities than any of the portable storage media in use. People need to carry data and earlier only had the option of using floppy disks which let them down every now and then and these disks were quite vulnerable to damage by slight bending, dust and even finger prints.

Pen drives can be put in your pocket just like a pen and this ease of use and versatility has made the pen drive very popular amongst power users who need to transfer huge files every now and then from one place to another.

Not only the users but computer technicians often carry a full operating system on their pen drives with the necessary diagnostics tools with them which otherwise would not be possible to use with out carrying the whole system to the service labs for testing and diagnosis which can now be done on site. It has made lot much easier for them as they can carry all the required tools, drivers, and antivirus kits on a single pen drive instead of a whole bunch of floppies and compact disks. Bigger capacity pen drives can carry an entire operating system on them for on site booting into the client computer.
