Scientists announced DNA storage devices capable of rewriting, erasing, and storing data for centuries

• University of Missouri researchers claim DNA hard drives can store, erase, and rewrite repeatedly
• Frameshift encoding converts binary data into DNA sequences for molecular storage
• Nanopore sensors read DNA sequences by detecting subtle electrical signal changes

The University of Missouri has announced progress on what it calls a “DNA hard drive,” claiming it can store, erase, and rewrite information repeatedly.

Unlike conventional HDDs or cloud storage, which rely on magnetic or solid-state media, this approach leverages the molecular stability of DNA.

The researchers claim DNA offers extraordinary storage density and longevity, which could make such a device both practical and energy-efficient compared with today’s data centers.
