The Asus ZenDrive U9M is an ultra-slim external DVD burner that supports both USB Type-C and USB Type-A. It comes with two cables for data transfer with PC and Mac. The high-quality, Zen-inspired design features fine, concentric circles, showcasing how beautiful technology can be. Compared to hard drives, flash storage, and other writable media that have a lifespan of about 8 years, the M-DISC writing technology engraves data into a patented stone-like layer that can withstand extreme environmental conditions, allowing for the storage of lifelong memories and important data for over 1,000 years.
