Some time ago I've read about 5D 'Superman memory crystal' heralds unlimited lifetime data storage which is about the data-storage technique which uses a laser to alter the optical properties of fused quartz at the nanoscale.
This kind of devices can potentially store 360TB of data (equivalent to 75,000 DVDs) on a standard-sized disc.
Is this technology real so far? Are there any available hardware devices for data storage based on that technology that you can recommend?
