Pen drives and USB drives refer to the same type of storage device. They are small, portable flash memory devices that connect to a computer through the USB port. The terms “pen drive” and “USB drive” are often used interchangeably.
What is a pen drive?
A pen drive, also known as a USB flash drive, is a small external storage device that connects to a computer via a USB port. Some key features of pen drives are:
- Portable – Pen drives are very small and lightweight, allowing them to be easily transported and stored.
- Rewritable – Data can be erased and rewritten on a pen drive multiple times.
- Plug-and-play – No drivers need to be installed. Simply plug the pen drive into a USB port and it is automatically detected by the operating system.
- Fast transfer speeds – Pen drives use flash memory which allows for fast read and write speeds.
- Durable – Pen drives have no moving parts, making them more resistant to physical damage compared to external hard drives.
- High capacity – Current models are available from 1GB up to 1TB of storage space.
What is a USB drive?
A USB drive is functionally identical to a pen drive. USB drive is a broader term that refers to any external storage device that connects via USB. This includes pen drives along with larger external hard drives and SSDs.
So in summary, all pen drives are USB drives because they interface over USB, but not all USB drives are pen drives, since the term USB drive also includes larger external storage devices. Pen drive is a more specific term referring to smaller, portable USB flash drives.
History of pen drives
The first USB flash drive was invented in 2000 by IBM and Trek Technology. It was called the Trek ThumbDrive and had a storage capacity of 8MB. Following this, other companies started manufacturing pen drives with increasing storage capacities.
By 2010, most pen drives had capacities between 4GB and 64GB. Currently, you can find high-capacity models up to 1TB. The increase in maximum storage capabilities over time has made pen drives a viable storage option compared to other external devices.
