I have a 4 TB Seagate external USB 3.0 drive and a 2 TB Toshiba USB 3.0 drive that are backup drives for my Toshiba 17" Laptop that I use a great deal. I run Acronis incremental backups and a weekly full backup to the Seagate. BTW the Seagate was $116 on Amazon.com and has 200 GB of free cloud storage if wanted.
