…is the 5D Data Storage! It could store 360 terabytes of your photos and videos in full resolution!
Now, there’s no need to hesitate in shooting RAW and 4K!
The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C) opening a new era of eternal data archiving. As a very stable and safe form of portable memory, the technology could be highly useful for organisations with big archives, such as national archives, museums and libraries, to preserve their information and records.
