New 'DNA cassette tape' could solve global data storage crisis

Scientists from the Southern University of Science and Technology in China have developed an innovative “DNA cassette tape” to tackle the growing global data storage crisis. This technology leverages DNA’s exceptionally high data density to store vast amounts of information in a compact, durable format that can last thousands of years without electricity. The system encodes digital data into DNA sequences, which are then stored on a physical tape made from a polyester-nylon blend. Barcode patterns printed on the tape create millions of addressable sections, allowing rapid access to specific data segments. A protective crystalline layer preserves the DNA, preventing degradation over time. The researchers demonstrated the system’s ability to quickly store and retrieve digital images, completing complex data operations within 50 minutes. A single 328-foot DNA cassette tape could potentially hold over 3 billion songs, equivalent to 36 petabytes of data—comparable to the storage capacity of 36,000 traditional hard drives. This DNA-based storage offers a promising alternative to conventional hard drives and servers
