Portable drives are external storage devices that allow users to save and transfer data easily. They come in various forms, including USB flash drives, external hard drives, and solid-state drives (SSDs). These drives connect to computers and other devices via USB or other interfaces, providing a convenient way to back up files or move data between locations. One of the main advantages of portable drives is their compact size, making them easy to carry in a bag or pocket. They are widely used for personal and professional purposes, such as storing photos, documents, and software, ensuring that important information is always accessible.
