Are you looking for not one but 2 external HDDs? You want an HDD bundle or duo pack. One for you and one for your friend, colleague, or family member. Or just 2 for yourself. An external hard drive is a device you can store files on, such as photos, movies, and videos. You can choose between different storage capacities, such as an external hard disk of 1TB, 2TB, or up to 20TB. There are also bundles with a data recovery service, so you can optimally protect your data for a longer period of time.
