At just 9.6mm thick, the HC660 is at the apex of light and stylish external hard drives, available in 1TB and 2TB storage capacities. Easily store your media and files, including the highest fidelity content, without worrying about running out of space. ADATA 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 whilst also making sure the surface paint won’t chip off or dull.
