A pen drive, also known as a USB flash drive, is a portable data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable, and much smaller than an optical disc, weighing less than 30 grams. Here are some key characteristics and uses of a pen drive:
-
Storage Capacity: Pen drives have seen a significant increase in storage capacities over the years. As of 2023, 2 TB flash drives were the largest currently in production, with capacities ranging from 8 GB to 2 TB.
-
Functionality: A pen drive is used for storing and transferring audio, video, and data files from a computer. It is simple to use, as the user inserts one end of the drive, equipped with a USB connector, into the USB port on a desktop or laptop and activates it. Files can then be dragged and dropped or copied and pasted into the memory.
-
Technology: Pen drives use flash memory, which stores data in blocks rather than randomly, allowing for more information to be stored at a lower cost. They are also non-volatile, meaning they can retain data even when there is no power source.
-
Advantages: Compared with floppy disks or CDs, pen drives are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts. They are also less vulnerable to electromagnetic interference and surface scratches.
-
Usage: Common uses of pen drives include storage, supplementary backups, and transferring computer files. They provide an inexpensive and reusable way to transfer data without the need for the internet.
In summary, a pen drive is a versatile and convenient data storage device that has evolved to offer large storage capacities, ease of use, and durability, making it a popular choice for personal and professional use.
