A portable hard disk is an external storage device that connects to a computer or other device via a USB or other type of interface. It is designed to be small and easy to carry, making it a convenient way to store and transfer data between different computers or devices.
Portable hard disks are typically powered by the device they are connected to, so they do not require an external power source. They come in a range of storage capacities, from a few hundred gigabytes to several terabytes, making them suitable for storing a wide range of digital files, such as photos, videos, music, and documents.
Portable hard disks are a popular choice for people who need to store or transfer large amounts of data, such as students, professionals, and travelers. They are also commonly used as backup devices for important files and data, providing an extra layer of protection against data loss due to hardware failure or other issues.
