Pen drives are typically small enough to fit in a pocket or on a keychain, and they use a USB connector to connect to devices. They are a convenient and portable way to store and transfer data.

Typically, they range from 4GB to 256 GB. They use non-volatile memory, which means that the data stored on them is retained even when the device is not connected to a power source. They are also relatively inexpensive compared to other storage devices, such as hard drives or solid-state drives.

Flash drives are also recognized for their huge storage capacity and quick data transmission rates. They come in a variety of capacities ranging from a few gigabytes to several terabytes, allowing users to store a wide variety of items such as documents, images, music, and video. They are also long-lasting, with most types resistant to water and stress, making them suitable for usage in a range of settings.
