Many computers no longer come with much hard drive space, as lots of information is now stored in the cloud or in multi-terabyte external hard drives, which have become affordable. That said, it’s important to make informed decisions about where you save your files. People whose careers depend upon safe file storage—those who edit film, present decks, program games, write dissertations—keep their work on portable hard drives. The next great American novel is probably on a drive in someone’s backpack. Since the cloud requires an internet connection and a trust that data companies won’t lose your work, having a sturdy physical device to back up your digital information is a responsible move. Here are some of our favorite portable hard drives currently on the market.
