As time goes by, it seems like we always need more storage. Even a 128GB phone will fill up with files eventually, and for many, those files are photos and videos that can’t be easily replaced. The 4TB Seagate Backup Plus Portable Drive ( $149.99 for 4TB) has the capacity to store hundreds of thousands, if not millions, of pictures and videos, as well as files from your laptop or desktop. It has the same capacity as the Seagate Backup Plus Fast$229.99 at Dell, a top pick in the category, but at almost half the cost per gigabyte. That means that for general backups and storage purposes, the Seagate Backup Plus Portable Drive is our Editors’ Choice for portable external hard drives.
