A flash drive is a portable storage device using flash memory, while a pen drive is essentially a brand-turned-generic term for the same device.

Key Differences

A flash drive is a universal term for a small, portable device that uses flash memory for storage. In contrast, the term pen drive originated as a brand name but has become a generic term in some regions, often used interchangeably with flash drive.
Both flash drive and pen drive serve the primary function of data storage and transfer. The terms are often used synonymously due to the shared functionality.
The term "flash" in flash drive denotes the use of flash memory technology, which allows data to be electronically erased and reprogrammed. Pen drive, on the other hand, doesn't indicate the technology but rather was popularized by the brand.
When considering purchasing, one might see both terms used on packaging or in product descriptions. Whether labeled as a flash drive or pen drive, they perform the same basic functions.
Globally, the term flash drive is more widely recognized and used. However, in certain regions, pen drive might be more commonly used, but both refer to the same type of device.
