The lightweight and portable 1TB G-DRIVE ev ATC with Thunderbolt from G-Technology is a rugged, bus powered, all-terrain drive solution with a tethered Thunderbolt cable that helps shield and protect a removable G-DRIVE ev RaW USB hard drive. While properly encased in its enclosure, the drive is well protected against falls up to 6.6′ / 2.0m on a carpeted concrete floor. The watertight enclosure will float, and if it happens to become submerged, the watertight compartment will protect the drive in up to 1.0′ / 0.3m of water for up to 30 seconds. The watertight compartment will also help to further protect your data from pressure, shock, and dust. The ev All-Terrain Case is compatible with the Evolution Series, which also fits the G-DRIVE ev or G-DRIVE ev SSD.
