Just 9.6mm thick, the HC660 is at the apex of light and stylish external hard drives, available in 1TB and 2TB versions. Easily store your media and files, including the highest fidelity content, without worrying about running out of space. We created the HC660 to look great and be durable, so it uses a scratch and damage-resistant sandblasted metallic surface. It is electroplated to ensure it maintains its looks for a long product lifespan: surface paint won't chip off or dull and the grooved texture will remind you of the HC660's fusion of fashion and utility for years to come. Thanks to meticulous craft and balancing, the HC660 is nearly the same height (or thickness) as a standalone 2.5-inch internal drive. Its durable and stylish enclosure provides great looks and protection without adding bulk or weight. We've employed sandblasted and electroplated metal in the HC660 enclosure to deliver strong resistance against scratches, paint chips, fingerprints and smudges. The coming together of science, engineering and fashion make this possible, proving that delicate beauty and tough performance can go together and that an essential storage device can be elevated to a style statement. Think of your games, videos, photos, documents, work projects and pretty much any other content squeezing into a slim form factor. That's great space that slips into a pocket with ease. Choose 1TB or 2TB, both are plug n play and unlock extra space right away.
