Imagine the times when people had to make multiple copies of handwritten notes just to be able to preserve important information. Too much hard work, right? With the invention of technology, human lives became easier and enormously difficult tasks became less complicated. Our methods of storing data also took a shift from laborious writing down of data into, saving it on our custom pen drive. Not only this change saved millions of data from getting lost but also, it paved way to a lifestyle where there is no limit to how much you can store, retain and retrieve. With advancements in technology through decades of efforts, we finally got blessed with the miraculous invention of pen drives.
