New DNA HDD can be ‘erased and overwritten repeatedly’ — University of Missouri researchers aiming for next-gen thumb-drive-sized storage

University of Missouri researchers are developing a DNA hard drive that can be erased and overwritten repeatedly, moving closer to practical, rewritable DNA storage. The project aims for a thumb-drive-sized storage solution with simplicity, speed, and rewritability. The team has developed a method for storing, erasing, and overwriting DNA data efficiently, leveraging frameshift encoding and nanopore sensing technologies. While the project holds promise for long-term energy-efficient storage solutions, it may take time before DNA-data thumb drives become commercially available.
