Built with the form factor of a credit card, the 1TB One Touch USB 3.2 Gen 1 External Hard Drive from Seagate lets you seamlessly scroll, edit, organize, and directly stream a large collection of stored photos and videos. Beneath its black exterior, the One Touch is equipped with a 1TB hard drive and a bus-powered USB 3.2 Gen 1 (USB 3.0) interface. The One Touch is formatted as exFAT, meaning it will work with both Windows 7 and later as well as macOS 10.12 and later without the need for a reformat. However, a reformat may be required for use with Apple's Time Machine.
