For example, Microsoft is examining the possibility of using lasers to etch data into quartz glass, or storing information in hologram form inside crystals. New developments in the field of tape storage, the current leading choice for archival use cases, are also promising. However, one new storage medium in particular appears to have all the necessary attributes: deoxyribonucleic acid, or DNA. Researchers have found a single gram of DNA is capable of storing 215 PB (220,000 TB) of data.
