Flash Drives

A flash drive, also known as a USB drive or pen drive, is a small, portable device that uses flash memory to store data. It is typically plugged into a USB port on a computer or other compatible devices. Flash drives come in various storage capacities, ranging from a few gigabytes to several terabytes.

SD Cards

On the other hand, an SD card stands for Secure Digital card and is a type of memory card commonly used in digital cameras, smartphones, and other portable devices. SD cards are available in different sizes and formats, such as standard SD, microSD, and miniSD, with varying storage capacities.

Features and Benefits

When comparing flash drives and SD cards, it is essential to consider their features and benefits to determine which option best suits your needs. Here are some key points to consider:
