Edited by Aimie Carlson || By Janet White || Published on December 4, 2023
A pen drive is a small, portable USB flash storage device, while a USB drive is a broader term for any storage device using a USB interface.

Key Differences

A pen drive, commonly known as a USB flash drive, is a compact, portable data storage device that connects via a USB interface. USB drives encompass a wider range of storage devices, including pen drives, that use a USB connection to interface with computers and other devices.
Pen drives are characterized by their small, pen-like size, making them convenient for transport and use. USB drives can vary in size and form, ranging from the compact pen drives to larger external hard drives that also connect via USB.
Pen drives typically have solid-state storage, which means they have no moving parts and are durable. USB drives include both solid-state drives (like pen drives) and mechanical hard drives with USB connectivity.
The capacity of pen drives can range from a few gigabytes to several terabytes. USB drives, being a broader category, can also include high-capacity external hard drives offering much larger storage space.
Pen drives are often used for personal data transfer and backup. In contrast, USB drives, as a general category, can be used for a variety of purposes, including professional-grade storage solutions and network connectivity.
