Ultra-slim through smart engineering Thanks to meticulous craft and balancing, the HC660 is nearly the same height (or thickness) as a standalone 2.5” internal drive. Its durable and stylish enclosure provides great looks and protection without adding bulk or weight. Gorgeous textured surface 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. Lots more capacity in a slim form 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. Keep Errors and Bad Sectors at Bay Lesser external drives continue to work even when dropped or encounter a shock, resulting in errors and bad sectors. With ADATA’s proprietary shock sensors, all drive activity will cease when a physical shock is detected. Once in the clear, activity resumes. Youre kept fully informed with a clear status indicator.
