Digital storage devices are tools used to save and retrieve data in electronic form. Common types include hard drives, solid-state drives (SSDs), and USB flash drives. These devices store information such as documents, photos, and videos, allowing users to access their files easily and securely. The capacity of digital storage devices varies widely, from a few gigabytes (GB) in smaller USB drives to several terabytes (TB) in larger hard drives. They can be internal, like those found in computers, or external, which connect via ports. Digital storage is essential for both personal and professional use in today's technology-driven world.
