  6. Speed and Performance: The speed and performance of an external hard drive can vary depending on factors like the rotational speed of the internal disk (measured in revolutions per minute or RPM) and the type of connection (e.g., HDDs are generally slower than SSDs, but they offer larger storage capacities).

  7. File Transfer: External hard drives are ideal for transferring large files or backing up entire systems quickly. They are commonly used by professionals who work with large multimedia files like video editors and photographers.
