An external storage device, often known as a portable hard drive, is a crucial tool for expanding the storage capacity of an iPhone. These devices connect to an iPhone through wired or wireless means and provide additional space for storing various types of data, including photos, videos, music, and documents.
External storage for iPhones offers numerous advantages. It enables users to overcome the limited storage capacity of their iPhones, which can become a constraint when capturing high-quality photos and videos or downloading large files. Moreover, external storage provides a convenient way to back up important data, ensuring its safety in case of device loss or damage. Historically, external storage devices have evolved alongside the increasing storage demands of mobile devices, becoming smaller, faster, and more efficient.
