What Does an External Hard Drive Do?

External hard drives provide users with additional external storage for storing important files or backing up the data stored in the internal drive. They are connected to computers via FireWire connections, USB or wirelessly.

Since they are not housed within the computer system, external hard drives usually have their own portable encasement. They also have larger storage capacities compared to other forms of external storage, such as flash drives and DVDs, making them the ideal choice for externally backing up large data files. The main advantage of external hard drives is that they are portable and flexible. This means they can be easily transported and used with any computer.
