Seagate will soon be the first to launch an external hard drive that requires nothing but a USB connection for power. The "Innov8" features 8TB capacity (equivalent to over 2 million songs, 4 million photos, and 800 HD movies) with 200GB OneDrive cloud storage on top; it supports both USB-C and USB 3.1, and includes Seagate Dashboard software which features one-click and scheduled backups. Finally, the Innov8 is comaptible with Lyve for easy photo consolidation.
The drive is beefy in appearance, which could be a good or bad thing depending on your tastes. Either way, it's awfully sleek. It launches in April through Seagate.com, Amazon, and elsewhere and goes for $349 MSRP.
