The drive is fully USB powered and does not require an external power supply, allowing you to take up to 4TB of videos, music and pictures with you on-the-go. Take further advantage of the fast USB 3.0 interface with transfer speeds up to 220MB/s. The included Seagate Dashboard provides scheduled and automatic backup options for your computer, social networks and even your mobile device. Install the free Seagate Mobile Backup app on an iOS or Android mobile device to back up all of the pictures and videos from the device to the drive or the cloud. Back up mobile devices via a WiFi connection while at home, or use services like Dropbox or Google DriveTM while on-the-go, away from home. The metal design fits easily in a computer bag or backpack, and helps resist against scratches and fingerprints during transport. For the first time, users can store as much data as a 3.5-inch desktop drive in a portable drive. Use the Save and Share features to download and upload content from your social network sites like Facebook and Flickr. Even photos you are tagged in can now be backed up to the drive. Install the pre-loaded NTFS driver on a Mac® computer, and use the drive between Windows® and Mac computers without having to reformat the drive.
